Swiped from the MTBR Homepage (a good place to check out) www.mtbr.com This was part of a product review of Mavic UST wheels. 9/03/99 Update: Well with a lot of effort I finally managed to get a flat, while using the Hutchinson tires. Last Sunday on Overgrown trail in Los Gatos, I was trying with all my might to keep up with Francis on a super snake like down hill run. I was running at really low pressure on my front tire, (I'd guess it was around 20-23 psi). Charging through a series of tight corners, I did a two tire slide and nearly lost control. Standing up in my saddle to gain back the ground I had just lost I went flying into the next hair pin left hander a little tooooo fast. The front tire wouldn't respond in the heavy gravel and just kept going straight. I ended up having to lay down the bike (which was better than riding off the trail into a poison oak infested ravine). I inspected my bike and found that my front tire was almost totally flat. I cleaned out some of the rocks that had gotten stuck between the rim and the tire and pumped it back up and rode the trail out a little shaken, but otherwise without another problem. The tires have worked great ever since and my confidence has been regained. The very next day we rose early and met at Skeggs point, our favorite local spot. After chasing Francis once again and getting to the bottom of Manzanita trail (a super rocky, rutty section) my back wheel was wobbling pretty bad. Slamming the rocks at high speed with little pressure (around 27psi) I had dented the rims, but no flats! I'm pretty stoked about that. About half the time we ride through Manzanita, somebody comes out with a flat tire. I'd have to assume that if I was on a regular rim, that someone, would have been me.
