After getting two flats on pretty much brand new tires in one month, I decided it was time to learn the art of repairing tires. I ordered a mushroom plug gun (made by Stop & Go) for repairing tires while they are on the rim. http://www.stopngo.com/Contents/1075.asp Its not a permanent fix but will be very good to have on road trips in case someone gets a flat out there. I need to get some CO2 cartridges for inflating but that's about it. I also ordered some permanent tire patches that are basically a patch with a rubber stem in the middle. You put them on from inside the tire and insert the stem through the hole using a metal spike wrapped around the stem. They seem to work pretty well considering that I patched a tire last week and have now done spirited (though not rediculously fast) Idaho City and Bogus Basin rides. I've also taken the tire to ludicrous speed and everything is great so far.
