A friend of mine just bought a new mountain bike a few months back but now he realizes he wants a road bike to keep up. He's looking to buy one used off of Craig's list or through a LBS on consignment. What should he he look out for? He wants to spend about $800 and wants to get the most bike for the money obviously? Is there a "Blue Book" on used bikes anywhere?
People have mentioned having their nicer bikes stolen. My current bike wouldn't generate much interest in that area, but I'm planning on getting a much nicer bike. How do you recommend securing it? I have a Kryptonite cable lock and a Kryptonite old school U-shaped lock. The latter is difficult to put on my bike. Can the former be cut off easily? Going to work is no big deal because I just park it inside my office (secure building) but if I go for rides on the weekend, etc. and need to park it somewhere I don't want it getting jacked. Any suggestions?
Lastly, I'm still debating between getting a hybrid (Trek 7.5 or 7.7 FX) versus a decent road bike. I'm a big guy (still a little north of 300 LBS) and like a somewhat wider tire but I don't want to have my bike (by design) keep me lagging badly behind a roady. With rider ability being equal, how much speed/efficiency difference is there between a high quality hybrid and a decent quality road bike?
Thanks for your time.
