I have a new Trek 2300 that I bought out of town. My LBS doesn't sell Trek but are very good, I just wanted a Trek. I had the LBS tune up and the owner was going over it and he thought the rear looked off, the way the rim/tire sat. He measured it with a park tool that lays flat against the head and seat tube and has a arc that takes a measurement off the deraliur hanger. He then flipped it around and said the other side was off .25". He said it isn't as true as his paramount but that is what you pay for in a custom built bike and that with it being off my trek won't handle as good as if the measurement was closer. Do I have a problem or is this more of a standard with a mass production bike? Thanks, Steve

You can NOT look at the way the rim/tire sit to determine this (which is why he picked up a tool). If your rear wheel dish is off, it will look like your frame is off kilter. It is possible that the LBS dude does not know what he is talking about. On the other hand, if he does, and if he did measure correctly, you should be covered under warranty.

I'd get a second opinion.

BTW- a defective frame is not standard on any bike (if that is the case).

Yes that is why he checked it. All I do is ride and these guys have kept all my previous MTB in excellent shape. He said something about the dish and then he checked the frame. It was 1/4" off measueing with that tool. Sorry if I am ignorant, about the most I can do is adjust the deraliurs, R&R rims, change tires tubes, just the basics.
1/4" seems like a lotKerry Irons

I'd suggest doing some G2 by "nonchalantly" calling Trek customer service and ask them about their tolerances. "I was thinking about Trek bikes, and I wanted to know what your acceptable tolerance for frame alignment was," and see if you can get some reference points. At that point, you'd be armed with the information to get your frame replaced, which I think is the right thing for Trek to do (assuming your shop measured correctly).
I'll give them a call, (nm)ditchbanger

That's 1/4" with the tool but....Atombomber

only 1/8" off of center. You need to remember that you must halve the measured discrepancy. The frame might be able to be aligned, but would suggest trying to get a replacement first. I don't know how aluminum (specifically ZR9000) will handle the tweaking. If Trek does consent to a replacement but your specific frame is not in stock, try to upgrade to a 5500/5200 OCLV frame instead of waiting for Trek to build and/or paint a new 2300 for you.
