yeah quite big. we have a park in down that is a 2 mile circut, nice play to babewatch and beef up...every lap there is about a...30 seond climb or so...which i manage fine, but 10+ laps i start to slow up a little and turn that gear at about 20 rpms nothing but pain there...wouldn't have it any other way...i've had my fixie for about 2 weeks now...and i get it now...i'm hooked. btw my flip flop has a 16 on the other side still...my emergency gear.

I'm planning on doing the Tour De Corn, in chattam illinois...metric century...i think i'm gunna run my 48 13...we'll see half way through won't we...
