a) Cause then I can get the saddle up - cant see any other way I can get that higher with current set up. Crank length seemed an easy way to find 10mm
b) To continue to try and work out why I cant hold power on that bike (plan a turbo session on TT to see if I can eliminate a few things)
Probably won’t make a difference at your height, TBF.
If you’re grinding on Zwift to get the power out, you might want a bigger ring and longer cranks to get the torque down. (And I mean “laying the torque down” here, not decrease it)
I’ve left the 172.5mm 50/34 on mine and was “spinning” in 50-11 on Wednesday.
I really must put the 175mm 55/42 on for next Tuesday
I leave my saddle height well alone for the 2.5mm differences (my road bike 52/36 is 170mm)
With SRAM there are removable spiders could you just swap the speeder to move from 110 to 130? Or is the inner part that connects to the crank different?
I’m not sure I’m that strong tbh. What I also want to check is the power phases on the pedals. Im sure inside I have much less dead spots - where as outside I only seem to to have power on the down stroke;
