My guess is they kept the internals of the shifter and just changed the lever design. Probably costed too much to engineer the shifting mechanism into the mechanical mold or maybe it has some patent reason. I was so excited to see them at first thinking I could finally get Campy slam shifting with Shimano hardware on rim brakes (always wanted it ever since I used a Campy shifter). Imagine my surprise when I received them, and they would only do 1 shift into the harder gear

Maybe there is just a mechanical blockage inside the new style brake levers. Similar to what campy did in Ekar.
I almost doubt they could mount old mechanism inside the new style levers, because the position of the downshift lever is completely different in new vs old.

Wait, these do not use the same thumb shifter as the hydraulic R9 and RX?

Yes, no problem, there is space for at least 40T...

My canyon spectral 27.5 rear triangle is bent and I'm looking for a new frame.

I had my eye on the AM831 but after reading Snacks his topic and FullCarbonAlchemist's suggestions, on that frame the bottom bracket will probably be too low.

Does someone know a fully trail frame that would work better with 27.5 wheels and a 160mm 27.5 fork?

I have the same problem, and would love to know what frame did @jondb end up using, if at all?

Few days ago my Spectral AL EX 27.5 broke at the seat tube.
Crack propagated from the dropper post cable hole around the seat tube, snapping it completely.
Luckily it failed when I was going uphill, otherwise it would be "an interesting experience"...

The bike is 7 years old and was ridden very little, just 3160km.
It was my third bike, and I never used it "as intended".
I'm a road cyclist, and I did most of the riding with this bike on local "rough gravel" roads, with occasional smooth downhill trails.
No bike parks, no "big" jumps, no crashes... so you can imagine I was quite shocked that this happened.
I have several bike, some even 20 years old... never have I seen anything like it.

Also the bike never "suited me"...
I always felt I was sitting way back... feeling like I have to hold on for dear life when going up steep hills.
Probably due to quite old-school geometry of this bike.

Since it is just one year over the warranty period (just 6 years for Canyon  )... I do not expect getting anything from them.
I sent them an email, but after few days no reply.

So now I'm looking what to do with the components that are left over.

Unfortunately I could not find any true 27.5 bike frames in the "china town".
Most of the models on sale are 29/27.5+, so that makes use of my existing components quite a pain in the back.

The FM1001 looks "interesting".
It has relatively low BB drop, and I like the steeper seat-tube geometry, it would shift me forwards on the bike, which I missed on the Canyon.
Maybe if combined with 2.6" 27.5 tyres, the BB clearance would end up being acceptable.

Fork Axle to crown length of 27.5" 150mm fork is quite similar to 29" 140mm fork, just a few mm difference, so I guess that would work.

Dropper post diameter is also 30.9, like on Canyon, and other stuff like brakes and groupset should not be an issue at all.

Only thing that would probably need replacing is the rear shock...
Canyon uses "standard mount" 190mm / 51mm shock.
And Carbonda is Trunnion 185mm / 50-55mm.
Do you think it would be possible to run 190mm shock from canyon with Trunnion adapter, or would the linkage hit the frame when extended fully?
That would be quite nice, because it would raise the rear end ~10mm and make it even more "XC like" and I would end up with ~125mm travel, which I would actually prefer.

Anyway, if anyone has any suggestions, I would love to hear your opinion.

Spear in L is basically exactly the same as Pinarello Dogma F 56.

LR on the other hand is a bit longer and lower. Comparable to old Canyon Aeroad M or Giant Propel ML.

I like this staggered sizing options, maybe L could be even a bit more relaxed, it would fit more people.

I fitted Ltwoo TX 1x12s on my 2017 Canyon Spectral.
Upgrading from 1x11s SRAM GX.

I combined it with 9-50T ZTTO ULT cassette and YBN 12s chain.

Shifting performance itself is good, I can't say its any worse than GX.
It is reliable, predictable, shifts OK under load.
Indexing is good, easy to setup.

Quality of the components seems good.
The only thing that is a bit "iffy" is the cable guide on the derailleur, it is plastic and looks like it could break easily if something would hit the derailleur. Will see how it holds up...

What bothers me is the ergonomics of the levers, GX has much nicer position of the levers.
On TX you have to place your finger in a bit weird position to shift.

I did not experience any chain drops so far, but I do not run extremely aggressive trails.
My riding is mostly XC.
