Sorry if this has already been gone over. I did a quick search and found nothing.
I got a real good deal on some Kenda Superlite tubes in 700x18-20C size but I run 77x23C Vittoria Corsa evo CX tires and was wondering if it is safe to use these tires?
I'm guessing 3mm isn't going to make a difference but figured I better ask someone that may know more then me..... The last thing I want is a front tire flat while going downhill at 45+ mph.
Thanks in advance for answeing my stupid question
