One of the issues I have with the bicycle industry is there are so many different standards … for everything. Straight and tapered head tubes. Somewhere between four and a billion different bottom bracket standards. At least four different styles of rear axle spacing that I think of. Quick release skewers and thru axles. Need to get replacement disc brake pads? Good luck.
It must be maddening to be a bike mechanic and have to deal with everything being a little bit different. Don’t even both with Cannondale. Everything they do is weird. (Though Canyon and Trek are equally as bad at times.)
At least SRAM is attempting to reduce some of the madness with their universal derailleur hanger and their DUB bottom brackets. (But yes, now there is yet one more standard.)
