Hello,
I did a bike fit 6months ago and resulting specs were:
Saddle Height: 721mm (with 172.5mm Crank)
Pad Reach (BB to end of pad): 467mm
Pad Stack: 650mm
Could you please advise me on the 2 following scenarios?
1) Swapping only Crank:
Moving from 172.5mm to 165mm
New saddle height => would think ~729mm
Pad Stack: lower crank should be lower stack I'd imagine (as lower crank would open up hip angle)
Pad Reach: would that shorten reach as well?
2) Swapping Crank + trying to be more aero/aggressive:
New saddle height => would think ~729mm
Pad Stack: how much lower should I try? From 650mm down to 625mm or is that too big a jump? (although the shorter cranks should help)
Pad Reach: Shortening it from 467mm to ~ 457mm? Would I be correct in thinking that it's just a 'geometry' problem that could be solved via cos? Are any websites/sheets which can help?
Thanks,
