I put a bunch of miles on my new / used bike in the past few months and the chain started skipping and dropping. I brought it in and had the same convesation with lbs... I decided to do both. Why not? It's cheaper than car repair and I ride the darn thing near every day!

My dh thought it was excessive, though. Oh well. Worth it to me. I'm doing a century next weekend and I want that bike in ship shape.
