It is a good system. The shifts are crisp even with a load of power going through the pedals.

I've just had to replace my slx cassette though after only 890 miles which is disappointing given that I see people running thousands of miles on them.

Is there any functional difference between a Deore and an XT?

Obviously, the XT weighs less not is there any difference in the shifting?

I think Hyperglide + is excellent for a normal bike, and good enough or let's say pretty darn good for an ebike, although it has drawbacks.

The main one would be that it shifts fast and you can feel it as chain shift shock(nicely shown in the Linkglide vs Hyperglide animation), especially when under power.

I think the Sram Transmission will wear at least the same or even more due to people just abusing it because they believe the hype of shifting under load not effecting wear. I believe all the Transmission is doing is enabling a quiet shift and so giving a false sense of lack of drivetrain wear, time will tell if the price for it is justified.

I also believe the Transmission is a somewhat copy of the Shimano Linkglide system that was released at least a year before and had/has the so called LINKGLIDE's optimized gear gate design =? Sram shift ramp design...and also like the Linkglide the Transmission is slow-er in shifting because of this tech...just food for thought here...

Don't get me wrong I like new tech and am not saying the Transmission is bad, it does have one negative side though if we leave out the price...it is slow, to slow imo any mechanical shift system with a healthy shifting technique is faster and also quiet and efficient.

I would love to see more of Linkglide on ebikes.

I've done 1700km (1050 miles) on my full XT M8100 drivetrain. Think my chain is almost at 0.50% so I'll be replacing it soon. On the Hyperglide+ thoughts mine actually shifts better when under load compared to easing off the pedals. It does feel like a DSG gearbox and is very smooth when changing under pressure.

Linkglide is hard to beat on an Ebike for the non-pros, it's cheap, burly, shifts clean and purpose-built.
Sure, if you are competing, weight matters and you are going a lot more maintenance anyway and prefer a known/tried and tested drivetrain then HG+.
Combine Linkglide with a proper wax and it is outstanding.

Initially was the lack of parts in case something bent, risking the fact that it would need to go back to Hyperglide+ (riders seemed to dislike have to adapt to new gears mid season), but the most important was the fact that Linkglide takes more time to switch gears.

I can totally agree with everything you wrote, as I also said, Shimano Linkglide and Sram Transmission both shift much slower(same technology) than older drivetrains and I am pretty sure I wouldn't like it either because when you have an uphill flow going you need fast and precise shifts, so in this case Hyperglide + with slightly releasing pedal presure it enables a really snapy and precise shift. Although I haven't tried the Linkglide yet so can't say for sure if it would be to slow. From what I have seen for the Sram Transmission It is definitely to slow for me.

In my case with regular cleaning and lubing my SLX/XT Hyperglide + is still going strong after two chains(KMC 1200km(0,75 stretch) Shimano XT 1500km(0,5 stretch)), original SLX cassette, so far 90000 meters of elevation gain and 3700km distance traveled on an average terrain incline of 8,3%.

So yes Hyperglide + is a pretty good ebike drivetrain, the only thing I don't like is the chain jump shock when shifting down the cassette(smaller sprockets).

Linkglide on the other hand probably provides smother shifting and takes away the so called chain shock to the expense of speed. It all depends what you prefer.

The best would be a hybrid of both systems.

The best would be a hybrid of both systems.

I’ve kinda been using a hybrid/hack drivetrain system for almost three years now.
Shimano XT cassette, HG chain, Sram AXS GX derailer, eThirteen 34t chainring, Shimano 13t lower jockey wheel(recommended). Before I switch to this system I chewed through cassettes and chains fairly fast. I seem to be getting more km’s from my drivetrain now.

Three problems though;
1-too fast
2-too quiet
3-too smooth

Other than that, I’m not bending derailer hangers as much.

I keep a spare hanger and HG chain, and lube things up every few rides.

I have a similar setup(except the 13T) on my amish bike, like you said it's a solid performer. With the hybrid I actually ment a hybrid between Hyperglide + and Linkglide would be the best for an ebike.

The old Sram AXS is fast, but still slower than any mechanical drivetrain, especially Shimano's where the chain shifts as soon as you press the trigger vs Sram's where it shifts when you release the trigger.

So I still prefer mechanical for an ebike.

The lower jockey wheel may not be necessary (Shimano 13t). The original Sram lower jockey wheel (14t) works just fine. I installed this exact system on a friends eMTB but the axle diameter on the guide wheel wouldn’t fit properly …so I left the original Sram 14t lower jockey wheel. The narrow/wide wheel caused a bit of “ticking” noise for a few rides then settled in. It’s plastic so the chain probably wore the narrow/wide a bit. He seems to be happy with the shifting.

The AXS derailer system allows for some micro adjustments thru the app.

@Mario Antony Thanks for your input, I am of course perfectly aware of that. The reason why I used it was because It was factory spec on a new Giant Reign E+ 2022.

I was also wondering why Giant speced the SLX cassette with this chain, as like you say man losses the Hyperglide tech with it, but as I had it new I gave it a go.

To add some info on this here, I had a Hyperglide+ drivetrain on my amish bike before the Reign and so I knew/know how smooth it is.

All I can say the marriage of the Hyperglide SLX cassette and the KMC E-chain on the Reign ebike was good enough, but no where near the Shimano Hyperglide smoothnes.

The 0,75% stretch after only 1200km probably shows that they don't match to good.

 

[emtbeast]

Sometimes product managers spec components outside of the product family (like your bike with KMC on Shimano) due to stock or contractual arrangements set previously.

I know, that was my first thought also, availability, as this was the after Covid time, I remember that Shimano stuff was out of stock in a lot of online shops. I never tried XTR as I feel the same, usually also go for the best bang for buck

 

[theremotejuggernaut]

This about what I got from an SLX cassette and a 6100 chain that came standard on my Rise.

I do a lot of pedalling on my rides and love climbing but I'm not a pedal masher and make full use of the gears. They just didn't last all that well.

II reckon swapping the chain earlier would probably have helped. I've just fitted an XT cassette/ chain and I'm going to buy a second chain and rotate them to see if I get better mileage.

 

[emtbeast]

For the chain I would always go for one group higher than the cassette, always has great results with the XT M8100 chains.

I thought about XTR but I hot wax my chains and having to poke the wax out of every single hole just doesn't appeal lol
