q. for mike jacoubowsky

[jim beam]

mike, passed a guy on the way home tonight who was riding one of those
big tubed trek oclv frames, and the front & rear wheels were completely
out of plane with each other. literally, the front wheel was tracking
about 2" to the right of the rear. have you ever seen this before?
being carbon, i can't see how the frame could have been bent in a crash.
the wheels were inserted correctly - they were not misaligned &
rubbing the frame anywhere. i don't get it. have you seen a trek with
this kind of problem before?

2 inches? That's waaaaaay more than is even ridable, let alone desireable.
Are you sure it wasn't optical illusion?

I think that is the model that Trek for European customers.

Some european cities still have trams (the public transportation
vehicles that run in a track).

With this model, you can't get both _wheels_ stuck in the track. Its
kind of a safety issue.

But if you get the front wheel stuck, you still endo. I had the opportunity
to see that happen 5 feet in front of me with a buddy of mine. It was
pretty horrific.

Wow, leave for just a couple days to Las Vegas (for the industry trade show)
and come back to find the world's falling apart! Or at least my mind doesn't
seem to be tracking properly, but it's off way more than 2 inches. Don't
think it's physically possible to build a high-quality frame that would be
off by much more than 10% of that mount and not have the rear wheel hitting
the frame (or something else appropriately odd).

If you specifically *designed* the frame for massively untracking, I bet
you could do it. Just set front and rear triangles at an angle and
compensate for that at the headtube.
