More what doesn't work...
So it claims inner ring 36T- that isn't true.
The seat post clamp doesn't work.
And it may be hydro only*. So I'm thinking through options.
Have you tried normal compact cranks? Will you really notice a difference between a 34 and 36? Seems a shame to send back a bike like this because of a few teething issues. I'm sure the seatpost can be fixed with grease and carbon paste in all the right places
What broke?
