I was ridng a couple weeks ago with my brother in law. He had never ridden a road bike before so I lent him my old Allez. (Not really old, it's a 2006!)
Did a really nice 20 mile ride around the Suisun area. But on the way back to Fairfield I took a relatively flat corner at a nice speed and my bro-in-law tried to follow. However, since he wasn't used to riding the bike he panicked and said he was heading straight for the curb and crashed. Luckily it wasn't a hard crash but he did end up busting my carbon seat post in half and bending the crap out of my rear wheel.
He was okay and came away with only some minor scratches but I like his gung ho attitude. Aside from that "minor" incident he still was interested in riding again. I may have piqued his interest in road bikes. Although I'll have to work with him on cornering and stuff! hehe!
