Tire Confusion...
I have a Giant Talon 29'er. I've discovered that many mountain biking trails are over my head. Waay over my skills. So, I want to downsize the tire size of 29 x 2.5. I turned to the internet and searched 29" tires and could find nothing under a 29 x 2.0. So I stopped into the local shop and talked tires and rim size. He put on a decent tire that is labelled 700 x 40c. What.?? Fits the 29" wheel great. I didn't know this could happen. I thought 700 sized tires are solely for 27.5" rims.
Anyways, he did up the rear tire and I'm rolling nicely again. I left the front wheel at 29 x 2.5. Correct me if I'm wrong..... I can order a 700 x 42c for a 29" rim, correct.??
