I bought a Trek years ago that's still my primary road bike, but all that's left of it that's "Trek" is the frame. All the Bontrager parts that came on it I've replaced because they either wore out quickly, or sucked.

The bars it came with were quite flexy, and I'm not a very strong guy, so I upgraded those. The wheels lasted a year before the rims were severely concave due to brake wear; when a pot hole flat-spotted one of the rims I replaced them with a set of Shimano's - which now have more km's and have hit more pot holes than the Bontrager's ever did, and are still running fine. The Bontrager saddle sucked on rides more than a couple hours, so I upgraded it too.

I wouldn't say I hate Trek, but I'm certainly unimpressed with Bontrager, as there is much better equipment for the same money available.

Maybe Bontrager's high-end expensive stuff is fine, but I'll never know.
