(...) A bit more. I didn't have enough patches handy, so I used a small blob of automotive "gasket maker" to plug the hole. I didn't ride enough to determine how many months or miles the black goo was going to last, but it seems like it would work on small pin holes. I don't recommend it for large punctures, long cuts or cracks. Also, I had some slow leaks that were difficult to find using soapy water. (At the time, I didn't think to try the ultrasonic leak detector). So, I over-inflated the inner tube. I think it's probably 26 x 1 3/8: Not only did the soapy water detect the leaks, I could hear the air leak and also feel the air with my fingers. Also, the normal size of the tire is the mounted tire located behind the over-inflated tire. If I ever get around to buying a IR camera, I could try heating the over-inflated tube, and possibly see the air leak because of the temperature difference. -- Jeff Liebermann jeffl@cruzio.com PO Box 272 http://www.LearnByDestroying.com Ben Lomond CA 95005-0272 Skype: JeffLiebermann AE6KS 831-336-2558
