A mix, I think. For some reason, even though my dad showed me a hundred times (give or take fifty) I could never get the hang of it. I finally got it figured out last summer, and the age of 30. Better late than never.

I have 2 bikes that got new tires last summer. One was the mountain bike, and I was told they were busy and would be a day or two. I had them check some of their work from a few months earlier, and it cost me an arm and a leg. Nice tires tough.

The other one went to the other LBS. (The first one told me I couldn't put 25's on my rims, the second had to call another guy to be sure) He only asked I take them off the bike and bring them in, he changed the tubes and tires in a few minutes, and I was on my way.
