I DON'T KNOW!!!!!

I rode 30 miles on them yesterday and they seemed kind of cramped...when I wanted to ride on the straight bar. ANd my hands were hurting (thumb/wrist) alot until my friend did a tiny adjustment..(rotated them down a bit and scooched the seat forward a mm..) But my hands are my weak spot on the bike ...I'm pretty OK every where else.

I kinda long for 40cm...instead of these 38...but I am ignorant about bar geometry.... so I don't really know!!!


thanks for asking.
