Yes, and the XX SL is aimed at the top of the racing market. Somehow, Nino can win world championships on it, but it doesn't shift fast enough for Paceliners.

He would probably win if he used a 20 year old 9-speed drivetrain.

The marketing trick is making anybody think anything matters other than it not breaking in the middle of a race. If it breaks it will make you lose. If it doesn't it can't make you win.

Not that I've bought any high end eBikes but I would have a hard time not wanting to go with one of the eBikes with the internal CVT or other transmission inside the BB area + belt drive.

It has this huge appeal to me to come at those bikes with motorcycle influenced designs rather than performance bicycle design.

Centralized mass, all the heavy mass low, low maintenance, clean with no greasy chain mess, no derailleurs to adjust, no chain to clean, belt lasts longer than existing bike chains, the belts were already designed for higher power, etc..

If you're going to have a motor why do you want a derailleur at all. It's never going to have the pedal efficiency of a performance non-e bike. Might as well have as many motorcycle style benefits as possible, even if you stick with the chain.

Bicycle gearboxes have very large drawbacks that are still very much applicable to e-mtbs, and these drawbacks are more in the realm of "inherent physical limitations" than things that can be solved through product iteration.

They are already on the market though.. so it'd be a case of try them and see how they perform.

The big bike companies are not even really trying.. just sticking with the status quo.

These more forward thinking bikes are not even more expensive than what the big companies are pushing.

There are a bunch of compromises the derailleur system puts on the whole rest of the bike too, and eBikes exacerbate that with more weight and more power.
