I'm going out to Tucson AZ in December, and was wondering if anyone knows any good trails out in AZ. I don't mind some climbs, as long as they're not insane, but really enjoy free rides and more technical trails. I've been looking online and seem to be finding some conflicting information. Could anyone point me in the direction of some good trails/a good website to read up on trails? Also, where in Tucson can I rent a decent mountain bike? I'm not looking for top of the line or anything, but the ones that I saw online that can be rented look like crap.
