Possibly really stupid bike tire question

[patches31709]

You ladies are smart - please tell me what I'm missing. I need a new tube on my front tire. I went to check the size, and the tire (Bontrager T1) clearly says 700x25c on it. In a few places. However, the specs on Trek's site definitely say 700x23c.

I have a 2013 Trek Lexa.

I fully admit it's pretty shameful I can't figure this out, but I'll learn, I promise. Now what the heck size do I get?

You will be fine with a 700x23 tube or a 700x20 tube. I wouldn't go for a 700x32 as it will be too big/wide. Tubes run about $7-10.

I'd go to your local bike shop and ask them. Bring your bike if you are concerned. For a few dollars more, they will put the tube in for you, make sure it is seated on the rim correctly, and pump it up. I also recommend learning how to change your own tube and tires. This is especially helpful when you are on a ride by yourself and are 10 miles from home and get a flat tire. Bike shops often have free "tire changing clinics" several times a year.

This is what I was leaning towards, thanks! And I do fully intend to learn how to do it myself, I'm kind of ashamed that if I got a flat, I'd be stuck somewhere.

Thanks!
