Canyon makes great bikes and at a very good price. My issue is not really with them but with the attitude LBS's have towards them. Most LBS will offer better service and even do some things for free as long as you've purchased the bike from them. If you roll in with a Canyon they are probably going to nickel and dime you for and repairs, tuneups etc..

Now if you are mechanically inclined and can do most everything yourself then that cuts that aspect down quite a bit but if you are not, then expect to pay for anything and everything when you bring your bike to LBS.

This is just my opinion and all LBS's will probably react to a Canyon differently but I'd say if you are mechanically inclined then buy now. If you are not then it's gonna be a dice roll on how your local LBS is going to react to you rolling in with one.

As a quick example the LBS I shopped at in my previous city had a deal where when you buy a bike from them it came with free basic tune-ups for life. If you can competently do one yourself then not really a benefit to you but if you can't, the cost of tune-ups alone over a few years would add up quickly.
