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!

You'll be fine with the 18/23s.

No prob at all.

Where you might run into an issue was if you were to use them with something like a 28 or 32 tire.  Then it will stretch it out more and you run the risk of having a very thin membrane which could be easier to puncture.

But for your application it will be perfectly fine!

thanks for everyone's input.  do i need to adjust the psi at all when inflating?  I assume that I still stick with the tire's recommendation but thought i would ask

Yes, best bet is to go by the tire recommendation inflation pressure.
