  Component Straightening Process  
What we do... Just as frames, subframes and swingarms must be straight to ensure good handling; forks and triple trees must be within tolerances for proper handling.

To test for straightness, solid metal precision bars are placed in the triple tree. The bars strong and known to be straight. Now the known quantity from which the straightness of the triple tree can be determined.

With precision bars inserted in the triple tree, one method of determining the straightness of the triple tree can be gauged by placing a level across the two bars at both ends.

  The actual forks must be tested for straightness as well if used as a gauge. By placing a gauge on the fork and spinning the fork, the direction of the bend can be determined...

Once the direction of the bend is determined, application of proper blocking and hydraulic pressure will straighten the fork once again.

Current cost for frame and component straightening is $120.00 per hour. The better the bike is prepped, the less time it will take to complete the job. Frame routines take a minimum of two hours.
