Help me figure out whats bent - September 9, 2011, 10:19 AM

My monster goes down the road with the forks cocked slightly to the right. This problem arose after I low sided it into a jersey wall about three years ago. The only visible damage that resulted from the accident was bent handlebars and a broken brake lever; however once I rode the bike I noticed the forks were far off center. After I got the bike home, I loosened the pinch bolts and was able to get rid of the majority of the problem, but the forks still remained slightly off center. Since then Iíve searched numerous forums and followed several different how-tos but Iíve never rectified the problem. Iíve finally decided that I would like to get it fixed this winter. The following might help narrow down the problem:

On numerous occasions over the years, I've repeatedly loosened every pinch bolt on the front end then retightened them in various orders. I think itís safe to say that something must be bent.

When I replaced the fork seals this summer, I used some primitive measuring techniques and I do not believe the forks are bent.

I was thinking that possibly the lower triple is bent, but I don't want to start throwing parts at it until Iím a bit more confident that is the problem.

Any ideas or advice would be appreciated!

could you have tweaked the frame up at the attachment point for the triple?

have you tried static balancing the front wheel and seeing if the front wheel wobbles side to side?

I guess its possible but I don't think so. At least I hope not!

I've had two tires mounted since then, both of them were static balanced. The wheel is slightly bent, but that actually happened after the aforementioned accident.

This poor little bike has been beat into submission

If you have tried the loosen method numerous times, my bet would be on bent forks first, tweaked frame second.. I doubt it is the triple as the forks will typically bend before the triple will..

I am no expert. The triples are far more rigid than the forks. The bend order in a front crash from what I've seen and pulled apart usually goes forks > wheel > frame (at the neck) > triples.

More than one thing might be bent,

Sounds like there's a nut loose behind the handlebars.

Alright, I'm gonna call in a favor to a friend with a monster. I'll see if we can swap forks and wheels to see if I can narrow down the cause(s). Thanks for the advice!
