Went to pick up some tubes at the LBS. Wanted tubes that work with my 25c front and 28c back. LBS only had 23xc-25c bontrager tubes with the valve stem length I needed. Said these would work with 28's. What does the forum say? BTW- I already bought them, just wondering if I'm going to be riding on some maypops.
23-25c tubes on 28c tire?
