Subject: Tube Question (700 X 18/23)I went to REI to pick up a few new tubes this weekend and I am concerned about the sizing. I have 700 x 23 tires (Pro2 Race ) and I picked up a few 700 x 18/23 racing tubes. I think my old ones that were on my bike are 23/25s. Is this going to be ok or am I going to be prone to flats easier? Is is better to get 23/25s? They didn't have 2 in that size when I went there and that is why I picked up the smaller ones. Thanks! |
