Nice thanks. I saw a review on the hopes but I worry 155 would be like leddaling a kids bike. Good for the shorter legged.I’m running a ancient 68/73 XT 165 with a single narrow wide 32T

I paid 20.00 on fleabay - great chain line and good Q
Note that Hope have done testing with 155 and 150 - and found wattage barely suffers. I felt the difference in leverage for about five rides - and downshifted and upped cadence. After that it became completely natural.
Interestingly analysis of power output shows that shorter cranks are of more benefit to taller people - it means they have to move the higher mass of their legs less. Which is REALLY interesting I think.Nice thanks. I saw a review on the hopes but I worry 155 would be like leddaling a kids bike. Good for the shorter legged.
