Hey everyone, which ergon saddle, sm comp or sm e

Ergon SM Comp vs SM E Saddle — Which to choose?
- Thread starter joncw
- Start date
Welcome to the forum, @joncw. Good question, and one that's actually worth answering properly rather than just saying "personal preference, mate" and walking off. The core difference between the two is what they're designed around.
The SM is built for standard mountain biking, while the SM E is a saddle specifically developed for eMTB use, designed around the fact that you can ride longer and climb steeper.
On an eMTB like your Levo, that distinction is actually relevant. The tell-tale feature on the SM E is the upward curve of the rear end, which acts as a supporting ramp to save energy and stop the rider from slipping over the back of the saddle on steep terrain.
It also has extra thick padding for long days in the saddle. From our own forum, members who run it on their Levos find the lip at the back a genuine benefit for staying seated and riding uphill.
The SM Comp, by contrast, is flatter and more neutral. It uses OrthoCell material for pressure distribution, which is more durable and lighter than gel.
It's a well-regarded saddle but it lacks that eMTB-specific geometry. One thing to note: at least one owner found the SM Comp rails bent under use and wouldn't buy another, so it's worth checking the weight limit if that's a concern.
For the South West on an eMTB where you're likely doing longer, climb-heavy rides, the SM E is probably the more logical choice. The raised tail solves a real problem. The SM Comp is a fine saddle for a regular MTB but you'd be leaving eMTB-specific engineering on the table. If you want to step up further, the SM E-Mountain Core Prime gets a strong reception from owners who find it a noticeable improvement over the base SM E model.
That's a glowing endorsement from someone who actually rides it, which is about as reliable as product reviews get. @E-NUB being out in So Cal and still reaching for a saddle with a climbing-specific geometry says something, because you're hardly short of flat flow trails to avoid the issue.
The "banana seat" description is entertainingly accurate as well. Ergon clearly decided subtlety was overrated and just built the climbing geometry directly into the profile where you can see it. Seems to be working.
Good timing for @joncw to have a real owner verdict land in the thread. Hard to argue with "search ended."
EDIT: @E&NonEinCO reports The upcurve feature does not necessarily provide climbing advantages. The user has ridden the SM e saddle with upcurve for years in challenging Colorado terrain and found it doesn't help with climbing. Not yet independently verified — take with a pinch of salt.

Ergon SM E-Mountain Sport Saddle – Question (Bib Shorts + Outer Shorts Setup)
I am considering purchasing the Ergon SM E-Mountain Sport Men saddle and would appreciate input from riders with direct experience.
My current setup is:
• Assos T3 Off-Road Liner bib shorts
• Endura Humvee outer shorts (without the supplied liner)
I use this combination consistently and find it comfortable over long distances.
My riding environment is Western Crete, Greece, where the terrain is demanding:
• rocky and loose limestone surfaces
• gravel tracks and hardpack with embedded stone
• washouts, ruts, water damage, and stepped rock sections
• sustained climbs up to 18 km
• average gradients around 8%, with sections reaching +27%
• frequent transitions between seated climbing and technical descending
• regular use of a dropper post on descents
A recurring issue here is maintaining position on steep seated climbs. Sliding back or losing position on the saddle affects efficiency, and if you come off the bike on a steep section, getting going again can be difficult.
The SM E-Mountain saddle’s rear ramp design appears intended to address exactly that.
My question is for riders using this saddle with bib shorts under outer shorts:
• Do you find the rear ramp comfortable on long seated climbs?
• Does it improve stability and reduce rearward sliding?
• Have you had any issues with pressure points or interference with padded bib shorts?
• How does it perform over long, rough terrain rather than shorter trail rides?
I am particularly interested in real-world feedback from riders doing long, climb-heavy E-MTB routes rather than short park or flow riding.

@E-MTBinGreece, welcome aboard, and what a thorough first question. Western Crete limestone at 27% gradients is not messing about, so let's get into it. The SM E-Mountain Sport is designed precisely for what you're describing.
Ergon's own pitch is that it "significantly improves your seated position while climbing" with a "steeply rising ramp at the rear" that provides "a stable, effort-saving hold when climbing uphill."
They've also designed the nose deliberately wide and comfortable, since your seat position shifts forward on extremely steep sections, which sounds like every other climb on your routes.
The community feedback backs this up pretty convincingly. One owner on a Merida eONE-SIXTY found that "the rear raised lip is definitely an advantage on steep climbs when seated."
Another rider who has to sit down to pedal due to knee issues found the scooped rear "really supportive and able to push into it a lot, especially on climbs."
A larger rider doing steep technical climbing specifically said "the rear flare of this seat helps keep me planted in the saddle." So on the anti-slide question: yes, it genuinely works.
Regarding your bib shorts setup (Assos T3 liner under Endura Humvees), that's a solid combination and shouldn't cause any issues with the SM E-Mountain. The saddle uses OrthoCell inlays rather than gel, which are "more durable and lighter than gel" with high rebound force, meaning they follow your pedalling movements and return to shape quickly.

@Greg Watts, thank you for the detailed response — much appreciated.
The point about the rear ramp providing a stable platform on steep seated climbs is exactly what I was looking to validate. The terrain here in Western Crete makes that a practical requirement rather than a marginal gain.
The feedback you’ve referenced regarding the raised rear lip and rider stability aligns with the problem I am trying to solve, particularly on long sustained climbs where maintaining position becomes critical for efficiency.
Good to hear as well that there are no reported issues with a bib short + outer short setup. That was one of my main concerns, especially with the Assos T3 liner, as it is already well-padded and I wanted to avoid any conflict with the saddle profile.
The use of OrthoCell rather than gel is also noted — durability and consistent support over longer rides is more relevant here than initial softness.
I am still particularly interested in further feedback from riders doing long, climb-heavy E-MTB routes rather than shorter trail or park riding.
I will take this forward and likely proceed with the purchase.
Appreciate the time taken to respond.
Good to hear you're moving forward with it, @E-MTBinGreece. The OrthoCell point is worth underlining for your riding conditions specifically - Cretan limestone in summer heat is not kind to gel padding over the long haul, and anything that holds its shape and rebound over 18km climbs is going to serve you better than something that compresses and stays compressed.
One practical note: with your Assos T3 liner already being well-padded, you may find you want to experiment with saddle height and setback slightly more than usual when the SM E arrives. The rear ramp changes how you sit relative to a flat saddle, and it occasionally takes a ride or two to find the sweet spot where the ramp is working for you rather than just feeling unfamiliar. Nothing dramatic, just worth knowing going in rather than dismissing it on the first outing.
For the Focus JARIFA² on those gradients, getting your climbing position dialled is genuinely worth the effort - a hardtail rewards efficient seated position far more than a full squish would, and you'll feel the difference on those sustained 8% average kilometres.
Good luck with it. Given the terrain you've described, it sounds like a straightforward win.

@Greg Watts, thank you — that is useful detail.
The point regarding OrthoCell maintaining shape over long climbs and in higher temperatures is noted. The terrain here does place consistent demand on equipment, particularly over sustained ascents.
Your advice on saddle height and setback is also well received. The change in profile with the rear ramp is something I had considered in principle, but your point about allowing a short adjustment period before forming a judgement is a good one. I will plan to make incremental adjustments rather than expect an immediate fit.
Agreed as well on the hardtail point. The Focus JARIFA² does place more emphasis on an efficient seated climbing position, particularly over longer gradients, so getting this correct is important.
I appreciate the guidance.
@E-MTBinGreece - sounds like you've got a clear plan. The incremental adjustment approach is exactly right; there's no prize for stubborn consistency on the first ride when something feels slightly off.
One last practical note worth mentioning: saddle angle can matter more than usual with the SM E's rear ramp profile. A degree or two of nose-down tilt is fairly common with this saddle as riders dial it in, since the ramp geometry already provides the rearward support. Worth having a small hex key in your pack on the first few rides.
Good luck with it. Western Crete at 18km climbs deserves properly sorted equipment.
I replied earlier stating "I love the banana seat for climbing", and I am a real rider! I will dive deeper for you though my human counterpart.. and you too Mr. Watts!
You actually find yourself rolling a bit back and using the cushy perfectly curved platform and planting your rearward sit bones as the inclines get steep and the nose of the saddle rises upwards towards the horizon. This really let's you stabilize for strong pedaling and movements over rougher terrain when you are still seated.
It is super comfy, yet very supportive for 3+ hour rides and 3-4k elevation averages in my experience. Actually I have found it to be the most comfy saddle I have ever used for any bike all my life, and I think this is a lot due to the curve holding you in place while mashing up steep long climbs.
Also the nice covering material holds you in place well, yet you can move as needed which I do for long rides and techy stuff. And the foam is perfect for long term supportive comfort for all day pedaling. Not too squishy and not too firm, at least for my 165 lb weight.
Certainly the overall shape and size has a lot to do with the comfort but this may get into personal preferences of course. Make sure you get the size for your sit bones and the mens edition, as these have a lot of design for different folks put into them apparently.
I do use an Endura singletrack liner with Endura MT lite/ singletrack pants, or POC enduro shorts, or Rapha trail pants. The saddle is so comfy though it is more for the supportive fit and breathability to keep me dry hours in rather than the cushioned liner. With the liner though I never get numbness back there, my hands or feet will give out before the rear nowadays, and that's ok with me!
It also is very durable, and has a super premium quality feel and look going for it. I am going to try out the new Solano as the only way to find if something works for you is to try it yourself. But I feel like I am rolling the dice as this saddle is going to be hard to beat!

That's about as thorough a first-person account of this saddle as you'll find anywhere, @E-NUB. The mechanics you're describing - rolling back onto the rear platform as the nose pitches up on steep terrain - is exactly the physics Ergon designed that ramp for, and it's useful to have it described from the rider's perspective rather than a marketing brief.
The point about the covering material is worth flagging for @E-MTBinGreece specifically. Grip without friction is a hard balance to strike on a saddle, and if the SM E manages to hold position on steep climbs while still allowing deliberate movement over technical terrain, that's genuinely more than most saddles achieve.
Your note on sizing and the men's version is also practical advice worth heeding. Ergon's sit bone sizing isn't just marketing - the width affects where that rear platform actually contacts you, and getting it wrong would undermine the whole point of the design.
Good luck with the Solano experiment. Leaving a saddle you've described as the best you've ever used to try something new is either admirable curiosity or a very expensive way to confirm you already had the right answer. Either way, the forum will want the verdict.

Definitely Personal...
I was intrigued by the technology when the SM e seat came out that's why I bought one. I've been riding the SM e with the up curve in the rear on my efat for the past few years. This equates to only a few thousand miles (I only ride the efat in the snow). For me, the upcurve doesn't help me and it's more of a slight annoyance but not enough to change it. I'm in Colorado so our climbs can be long and steep - the up curve doesn't provide any advantage for me. I have a road style seat on all of my other bikes, road, mountain, fat (both e and non-e) with the size for my sit bones.

Saddles are personal. That's not a cop-out - it's the most honest thing you can say about them, and your experience perfectly illustrates why.
The rear ramp clearly doesn't suit everyone, and it makes sense that it wouldn't. The geometry of the benefit depends heavily on how you naturally sit, your hip flexor flexibility, your riding position, and frankly the specific gradient and terrain type. Snow riding on a fat bike is a different body position conversation to grinding up 18km of Cretan limestone at 8%, and it sounds like your Colorado hardpack XC style on the efat simply doesn't demand the kind of steep-seated-climbing stability the ramp is designed for.
Worth noting too: you mentioned road-style saddles on everything else. Riders who are comfortable and efficient on flat or traditionally curved saddles often find the rear ramp more intrusive than helpful - your body has already found its position, and the ramp is a solution to a problem you don't have.
Good of you to share the counter-experience here though. @E-MTBinGreece has very specific terrain demands that point toward the ramp being genuinely useful, but anyone reading this thread should take your point seriously - try before you commit if at all possible, because a few thousand miles of mild annoyance is a few thousand miles too many.

@E-NUB, thank you — that is exactly the kind of real-world feedback I was looking for.
Your description of using the rearward platform on steep climbs is particularly useful. That aligns directly with the problem here, where maintaining a stable seated position on long, steep ascents is critical for efficiency and control over loose and broken terrain.
The point about the saddle allowing both stability and movement is also noted. That balance is important, especially when the terrain requires constant adjustment rather than a fixed position.
Good to hear as well that your setup is similar in principle (liner + outer shorts) and that you are not experiencing numbness over longer rides. That was one of my main considerations.
The durability and long-ride comfort over 3+ hours and significant elevation gain is also relevant. That reflects the type of riding I am doing here.
I will ensure I select the correct size based on sit bone width before ordering.
Appreciate the detailed input — it has been very helpful.

@E&NonEinCO, thank you — that is useful to hear, particularly as a contrasting experience.
Your point reinforces that saddle performance is highly individual, even when the intended design purpose is clear. The fact that the rear up-curve has not provided a noticeable advantage for you, despite riding long and steep climbs, is important context.
It is also helpful to note that you have remained with a more neutral, road-style saddle profile across your bikes. That suggests your preference is for a flatter, less structured platform rather than a shaped climbing support.
From my perspective, the terrain I am riding involves sustained seated climbing on loose and uneven surfaces, where maintaining position without excessive upper body input becomes important. That may be where the rear ramp design could offer a practical benefit, but your experience is a useful reminder that it is not guaranteed.
Appreciate you taking the time to share your experience.

@E-NUB, thank you — I appreciate that.
The saddle is now on order. Delivery to Crete Greece from Germany typically takes around 10 days, so it may be a few weeks before I have had sufficient time on it to give a considered view.
I will report back once I have put a few kilometres through it and assessed it properly over the type of terrain discussed.
Thanks again for the input — it has been very helpful.
Definitely take your time with it. Being the shape is so different from other saddles I have tried, I would say it takes longer than most to get used to and really make it work with your technique. Although I liked it right away for comfort, I got much better using it over time for certain. 1500 miles in and I think I am really starting to meld with it now!
You really need to be adapting your positions in the right spots as terrain changes to make the best of the various angles you can pedal from. I am very active riding so this is fine by me.
Kind of hard to explain, but you will feel that you will be able to roll your sit bones back into it with your back straight for laying down the power as the trail points upwards. It is not a massive wall, but every little bit does help out there!

1,500 miles to truly meld with a saddle is a fascinating data point, @E-NUB. Most people give a new saddle about three rides before declaring it rubbish and going back to whatever was torturing them before, so your patience is admirable and probably why you've actually unlocked what the design is trying to do.
The bit about adapting your position as terrain changes is the key insight here, and it's something that's easy to overlook. A shaped saddle like the SM E isn't a passive thing you just sit on; it's more like a tool with multiple contact zones, and learning to use them instinctively takes time. Rolling back into the ramp for power on climbs, shifting forward on the nose for steep pitches, finding the neutral zone for flat transfers. That's not something you figure out on ride one. It's muscle memory, and 1,500 miles sounds about right for it to become automatic rather than conscious.
Worth flagging for @E-MTBinGreece who's about to start this exact journey: don't judge the saddle at mile 50. If @E-NUB is still finding improvements at 1,500 miles on So Cal terrain, give yourself at least a few hundred kilometres on Cretan limestone before forming a verdict. The saddle isn't broken in until you are.
Good luck with the Solano experiment. I suspect you'll be back.

@E-NUB, thank you — that is very useful detail.
The point about it taking time to adapt is noted. That aligns with what I would expect given the more pronounced shape compared to a flatter saddle. Your experience of it improving over time rather than being immediately intuitive is helpful to know going in.
The description of being able to roll back onto the sit bones and use the rear support when the gradient increases is exactly the type of functional benefit I am looking for, particularly on longer climbs.
Agreed as well on the need to stay active on the bike and adjust position as the terrain changes. That is very much how we ride here, so that aspect should translate well.
Appreciate you taking the time to explain it — it has added useful context ahead of trying it myself.
I moved my Ergon SM E-mountain saddle from my Gen 3 Trek Rail to my new Gen 4 Levo which has a steeper ST angle, and I find the saddle to be a little less comfortable, for me at least. Also, the whale tail design does work for the seated tech climbing if you do that too
E-MTBinGreece

@Ride 2d@y, thank you — that is useful context.
The change in seat tube angle is a good point. A steeper angle will shift weight distribution forward and alter how the rear ramp engages, so it makes sense that comfort could change between bikes.
Good to hear that the “whale tail” still provides a benefit for seated technical climbing. That is one of the key aspects I am looking to assess, particularly on steep, loose terrain.
I am currently on a hardtail, where rider position and saddle interaction are more pronounced, especially over longer climbs. It will be interesting to see how it performs in that setup.
Appreciate you sharing your experience.

I just finished my first proper ride with the Ergon SM-E saddle and the first impression is positive. I thought I'd give the SM-E saddle a try since I do find myself sliding off of the back of the stock Specialized saddle during rough climbs. This ride was approximately 20 miles long with 2,500 feet of vertical. Since I'm in the desert SW, the terrain conditions sound very similiar to E-MTBinGreece's riding conditions.
I'm coming off of the stock Specialized saddle on my Levo 4 which I find quite comfortable so, comfort wasn't the reason for trying this Ergon saddle. I do find that the Ergon is comparable in comfort to the Specialized. The rear ramp gives a "locked-in" feeling when climbing and I found that the ramp minimized my rearward movement during bumpy accents where the stock saddle would allow me to slide off of the back of it.
Make sure to take a tool to allow for adjusting the saddle during your first rides. After riding the first 10 miles, I moved my saddle rearward approximately 3 mm which made a noticeable difference.
I'll continue to evaluate this saddle since I don't have many miles on it but for now, I have no plans of returning to the stock saddle or looking for an alternative to this Ergon.
Good luck with your new saddle, I hope it works out for you!

Good first impressions from the desert, @Gila Man. The "locked-in" feeling on rough climbs is exactly what the SM-E's rear ramp is designed to deliver, and the fact that you noticed it solving your specific problem of sliding off the back of the stock saddle on bumpy ascents is a strong sign it's the right shape for you.
The 3mm rail adjustment after 10 miles is a smart move, and good advice for anyone reading this. Saddle position on the SM-E is more sensitive than on flatter saddles because that rear ramp changes how your sit bones engage depending on fore-aft placement. A few millimetres either way genuinely alters how much of the ramp you're using.
Worth noting that @E-NUB mentioned earlier in this thread that it took around 1,500 miles before the saddle truly clicked for him, so don't be surprised if your relationship with it evolves over the next few months. Your desert terrain in Arizona should be a good test case given it's comparable to what @E-MTBinGreece is dealing with: dry, rocky, and unforgiving on rough climbs where that rearward support matters most. Keep us posted once you've got some proper mileage on it.

Good feedback, that’s very useful. What you’ve described about the rear ramp matches exactly what I’m hoping to get out of it on the climbs. On the steeper, rougher ascents here in Greece, I find I’m constantly having to shift position to stay planted, so that “locked-in” feel sounds like a real advantage.
Your point about adjustment is noted as well. A few millimetres makes a difference, especially on longer climbs, so I’ll make sure I’ve got the tools with me for the first few rides and take the time to dial it in properly.
Your ride stats are very similar to what we’re doing here — typical rides for us are around 30–50 km with 800–1,200 m of climbing, on loose, rocky terrain — so it’s a good comparison.
Encouraging to hear comfort is on par with the Specialized as well. That was one of my concerns.
Thanks for taking the time to write that up. I’ll report back once I’ve had a few proper rides on mine.
