I recently bought my first ever road bike and the tires are listed as size 700x23/25c
Which setting do I use for my computer, 700x23 or 700x25? I've noticed that the distance I get from my GPS data logger is always just a little longer than what I get off my computer, and right now I have it set for 700x25.
I'm not sure what the 700x23/25 indicates.
Thanks for any replies.
