Race Tech 90mm fork springs 6th gen

Has anyone done this mod and was was your cut spacer length?

 

Sorry that I can't help you with a simple answer, but calculating the spacer length is not hard.

Install your springs and the two flat washers into the fork, and then measure from the top of the washers to the top of the fully extended fork tube, call that A mm.

Put a fork cap on the damper rod and loosely install the locknut in it's normal place, then slip the cupped washer onto the bottom of that, wind the preload adjuster out (to minimum) and then measure from the bottom of the cap (where it sits on the very top of the fork tube) to the bottom of the cupped washer. Call that B mm.

If you subtract B from A, that will be the distance from the top of the washers to the bottom of the cupped washer, with an uncompressed spring. Racetech usually suggest a spring preload of 15-20mm, so add that to the distance and that is your spacer length.

Probably best to err on the higher preload end (20mm) as it is easy to shorten the spacer if needed, a lot harder to make it longer!

 

Thank you very much.

 

Damn Cadbury, you have your shiet together I was going to say that.
