Trek rail rear shock upgrade ideas please

[Zed.]

I agree with comments already made that the piggyback on that Mara looks way too long to fit an aluminum Rail.

Manitou make 2 lengths of piggyback thinggy with the longer on 'Rail sized dampers (although can be bought aftermarket and aparently easily swapped

Manitou are having a sale (on their website) so lots of heavily discounted prices.....

^^ Usefull IF you live in USA / Canada but not so good in the UK as wont ship

After several short landings, unexpectedly, I found no sign of impact between the shock absorber and the frame. The bike is a 2022 rail5 size L and the shock absorber is a
Rock Shox Super Deluxe Ultimate RC2T Debonair (no Trunion) 2023 wheelbase 230 mm stroke 57.5 mm

If it was me I would let all the air out of the shock to be sure that the reservoir does not hit the downtube. Easily checked.

Fitted a Cane Creek DB Tigon - Standard 230 x 57.5 to my Trek Rail 9.8 , smart system 750, size M, MY 2022, fits great. Interesting shock as it has a coil and also an air shock feature to add progression and bottom out protection.

I see, if I'm not wrong, a fidlock bottle cage.. does the standard one not fit?
With this, can you have 500ml bottle or less ?
Thank you

(2022 Trek Rail Alloy Large). With an Ohlins TTX22m.2 coil shock the largest bottle I can carry is 600ml and had to modify a bottle carrier to as high in the frame as possible to prevent the top of the shock hitting the bottom of the bottle.

First ride yesterday on my 2022 Trek Rail (Alloy, Large) with Ohlins TTX22M.2 with 525lb spring. Thanks TF Tuned! Am 79-80kg Rail has Rockshox Pike Ultimate 150mm forks moved over from my Trek Fuel EX (ML) upgraded to 160mm C1 Air spring for the Rail. The Ohlins shock replaced the stock...

Thanks Irie... I asked Josepi because I have a M size too...

until now, for my knowledges, on the M only the EXT e-storia (see my post here) is compliant wuth the standard cage (500ml)

No idea, will find out this weekend!

I already had the fidlock on, it's a 450ml bottle, so not sure about the standard bottle cage.

The concept should make for a great ride on the Rail with its suspension design. Benefit of a coil ride but adding air spring for a more progressive ratio.

Same with Rail 7 gen3 XL and EXT e-Storia. But Rail with e-Storia is super good!

From your experience with both coil shocks how does the E-Estoria compare with the Ohlins TTX22m.2?

 

[mteebee]

My Deluxe select+ need service but it`s 4 years old and I think it`s better upgrade. Ideas? Trek rail 7 2020 aluminium size L fork rs yari (motioncontroll need replacement too). Air shock is ok I just ride trails with rock gardens no DH sessions. Price should be less than 400€, dvo topaz 2(if it fit?), fox dpx2 performance or rs deluxe ultimate...

I've been running a Manitou Mara (230x65) for a few months on my Medium rail5 and found it exellent, we have a few other dampers in stock...

Manitou Mara, Fox float x2 evol taken from My Mrs's S-works kenevo sl and an Ohlins Ttx air - all in 230x65.

curiosity (& mrs demanding my opinion of the Fox damper ) and trial-fit on the rail..

it fits in it's extended state (actually clears the seatpost.

but, clashes with the frame on compression (not full stroke of 65mm BUT the standard rail stroke is 57mm I believe) so didn't test-ride

so fitted the Ohlins and gave it a shakedown Saturday & Sunday @ Bpw

I'm ~110kg so no lightwieght!
same ~20%sag as riding red tech trails with some attempts at smaller jumps (white men can't jump?)

Manitou Mara 170psi
Ohlins 245psi
the Mara follows Manitou's low operating working pressure (I have Manitou Mezzer forks and run between 60psi & 70psi in the main & negative spring chambers depending on how I'm feeling!
whereas the standard-fit Rockshox forks needed a lot more - Rockshox rear damper needed over 350psi in its airspring to not constantly bottom-out)

both similar compression & rebound settings (basically open)

so, what do I think?

both the Manitou & Ohlins are good, similar support from their airsprings but I seemed to use slightly more travel on the Ohlins damping wise I found them as good as each other

I'll probably keep the Ohlins on the bike a little longer for a better appraisal but want the mara back as it just felt that little bit more comfortable

Spin the shaft 180 degrees so the knob is at the back.

I know it's an old post but sooo glad i read this. I've just been shitting it that it won't fit, so thought i'd scroll back. Just got to swap the spacers over. Cheers for the obvious and life saving answer will post a pic once I get it on

Is that Ohlins a TTX1 or TTX2?

 

[Paulquattro]

TTX 2

 

[Zed.]

Is that Ohlins a TTX1 or TTX2?

as Paulquatro says, TTX2

anyway, back on the Mara as its more comfortable
Ohlins springing felt harder (as you'd expect with 75psi higher pressure for same 'sag'') but both have same control

looking for a Mara pro now, think I need to try one

Rich.

I think the progressive rate issue on the Rail suspension is overdone. I ran the stock air shock a little but ended up with the Fox DH-X2 coil shock. It's been awesome. I come from dirt motorcycles and many full suspension MTB's over the years. I've rebuilt the rear shocks on many of them and even tweaked the damping components in some of them when it was necessary and possible.

I ride in very rough terrain, and this issue of the Rail not being ideal for coil rear shocks is exaggerated IMO. Maybe there is an imbalance with an air fork and a coil rear shock for some, and perhaps better balance can be achieved with a coil fork. That's what I did with a Marz Bomber coil fork. Still, so much preference can be applied when we're talking about suspension design, application, and component selection, so I'm not claiming there's a one-size-fits-all here.

I will suggest that perhaps some/many don't know how to tune their extensive options in the compression and rebound circuits in some cases to address some issues that they're blaming on the shock as a whole unit.

I can confirm this Rockshox Vivid Ultimate fits nicely 230x60. Gen4 Rail 9.8 size L.
Only a few rides in and it feels great. I've had plenty of coil shocks before and this feels very close. It's fantastic having proper compression adjustment and hydraulic bottom out.

How much would the rear travel increase by running this shock

 

[hongeorge]

I'll see your 230x60 and raise you 2.5...... this is a 230x62.5 on my large Gen 4

I know a 65 stroke will fit too, but I'm keeping it in the low setting, didn't want to overdo it.

 

[mustclime]

Suspension math, the rail comes stock with a shock that has 57.5mm of movement and has 150mm of travel.
150/57.5=2.61 suspension ratio.
If you put a 230x65 shock you just
2.61x65= 169.7mm….. if you run a 230x60 shock you will have 156.6mm of travel….high school math comes in handy once again.

my rail has a 230x65mm rear damper, @17stone I dominate nearly ALL of the extra travel

Rich.

 

[hongeorge]

Sort of... that 2.61 is an average - see the graph of leverage ratio from Rob's Rail review

By the time it hits 150mm, the progression in the frame design means leverage is roughly 2.4

So my extra 5mm of stroke is adding 2.4 *5.0 - about 12mm

 

[hongeorge]

Have a few rides on the Vivid, not done much to it other than set sag, but main thing I've noticed is that I don't bottom out, and the bike feels that little bit calmer at speed in the rough, maybe a little plusher. All in al,. very happy with it so far.
