At that level the bikes are usually custom made and certainly custom fitted.
Handing everyone a Schwinn Varsity won’t cut it.
I have a triple chain ring on the front sprockets of my road bike to help with hill climbing. There are cyclists I know who think that’s cheating.
The internal motor is brilliant but certainly is cheating.
I went with a single ring in front on my mtn bike (a 1x10 setup) There are cyclist I know who think that's just dumb.
And they tell me!
Nah, that was what we used to call a "touring rig". Need the gearing to haul touring gear up the hills.
