650c versus 650b
Hello all,
I am leaving on a bike touring trip tomorrow taking my road bike which has 650b tires. I live in a very small town with minimal access to equipment. I know I should have addressed this sooner but this is the situation I’m in. The only spare tubes I can buy are 650c. I know it’s not ideal but I am wondering if it would be safe to bring and use these. Ordering online isn’t an option for me, and if there is a bike shop reasonably close to me on the touring route I’ll try and pick up 650b tubes there. Thanks!
