What
mstateglfr wrote is true. This particular bike originally came with 25mm tires but will take 28s no problem. For this vintage road bike ride in Cambria at the end of April, part of my fun is to ride a bike as it was originally equipped. This means 25mm tires, BioPace 42/52 with a 13/24, and all the rest. Some folk modify their road bikes with wider tires, among other things, and we all have fun.
