You were comparing two different bikes of different sizes, gear ratios, and geometries.
you're right, 10mm difference is very minimal to notice any difference from me (unexperienced rider). if by pedaling larger circles, wouldnt that mean i wont be spinning out as soon as if im on 165mm arms?
so comparing the 2 different gear ratios - 75.2 gear in vs 81 gear in - wouldnt the 75.2" be easier to ride and stop vs the 81"?
here are some more measurements and specs of the bike to give you an idea on the dimensions of each bike.
mine (53cm rush hour) / his (56cm subrosa):
gearing - 39/14 (75.2") / 48/16 (81")
top tube length (center to center head tube - seat tube) - 21in / 22.5in
seat post angle (measure from center of BB) - 14.2* / 14*
seat height (measure from center of BB to top of seat) - 27in / 27.5in
head tube angle - 16.5* / 16.5*
stem - 80mm / 90mm
handle bars - nitto drop bullhorns 40cm / volume cutter risers
pedals - MKS gr9 with soma cage and MKS single strap / Odyssey BMX platform with Blaq strap
wheels - front and rear = 27" / front and rear = 27"
wheel base (center front hub to center rear hub) - 39in / 39in
