On the schwinn I'm fixing up, I am rather pondering possibly converting to 700c. At first i wasn't going to but now I'm thinking again I might want to.
The thing that is confusing is how do i measure the caliper reach so I can get the proper replacement calipers in there?
Currently the bike has a set of sidepull single pivot sidepulls and the front one is rather bent up. Even if I do not convert to 700c, I still would like to convert to double pivot caliper brakes but I'm not sure how to measure the calipers to get the right size, standard or long reach.
