Difficulty with the right size

KevinHartman

Hi,

I would like to buy the bmc alpenchallenge ac01 alfine. I was at the store yesterday to check them out they only had m available and it was a tad too big but I didn't have the chance to compare them to the small frame size. On the bmc site is no size guide so maybe someone here can help me out.

My height : 166cm
Leg length: 75cm
Arm length from Palm to elbow: 35cm

Size guides are pretty useless anyway...but at 5'4" you're a long way below average height so a small would be the sensible starting point, if that's still too long you could replace the setback seatpost with an inline.
