Wheel upgrade help: 630 (27 x 1 1/14) Steel to Aluminum
Ive been upgrading an old 80s bicycle and Im having alot of fun working on and riding it. The thing is mostly steel, including the rims (ISO630 27x1 1/4"). Im looking to drop the extra weight and get some better braking with a thinner aluminum rim. I'm not sure what thinner size I will be able to find in aluminum that will fit my current brakes as well as frame. I was unable to find info on Sheldon Brown's website.
Does anyone have any idea what thinner rim would work for me?
