I've been working in a bike shop for four years. The only shops that have year-end sales (or any regular sales) are the shops that inflate their prices in the first place, so you're not really getting a discount.

The margin on bikes is very small. Dealers make a much better margin on clothing and accessories. It's very tough for a dealer to discount a bike, especially the higher end ones (the margin is smaller on the more expensive bikes than on the less expensive ones).

A bike is a bike is a bike, whether it's a 2007, 2006, 2005. Many models don't even change that much from season to season. And some prior-year models are better (especially component choices) that the new models. All you'll see at this time of year is low inventory while the dealers are waiting for the 2007s to trickle in.

Don't make a significant purchase like a bike because you're going to save a few bucks. Make that decision based on the shop -- is it a shop you want to develop a long-term relationship with? And base your decision on the bike -- is this the bike that absolutely rocks your world (fit, color, component choices, etc).

ps -- how do you spell trickle?
