From: Downtown Detroit, Mi.
Bikes: Surly LHT, 94 Cannondale track bike, 80's Cannondale track bike, 60's Raleigh 5 speed, 1888 Eldridge wood wheel track bike and my old 76 DG BMX from when I was a kid.
My ultegra, dura-ace and 105 cranks are all 130 BCD and not 135 but you still cant go smaller than a 39 tooth chain ring. One tooth smaller in the back is like 3 and 1/2 larger in the front so you can get the most bang for your buck in the back cassette. So you can use a 9 speed cassette that is 11 to 34 tooth to help zip yourself up the hills.
