Hey I've got an old Schwinn Sprint Bike with vertical dropouts and i wanna convert it into a ss cyclocross bike. I'm a little bit confused on what gear ratio i should run on it...i had in mind something close to a 40/17 but im not sure if that will work for cyclocross well or not. I've ridden my friends bianchi San Jose which i believe has a 42/16 on the freewheel setup and that felt pretty comfortable but i was still considering getting a ratio that is just a little bit smaller so i can climb easier. What ratio do u think i should run on the bike? Im in need of help greatly...i definatley dont wanna buy a new crank and freewheel that im not comfortable with!
