Fox Performence 120MM is infact 135MM?

ForMartha · Apr 9, 2022

Heya,

Just installed the new MRP Ramp control in my fork and as I was looking at it, it seems like the fork isn't 120MM as I thought.
So I used my measuring tape and found out that from the seal to the begining of the CSU entry, the fork measures 135MM.

Anything I'm doing wrong here?

Thanks,
-M

My stock 2020 34 120 travel Step Cast measured 130mm from lower leg seal to the fork crown.
I figured that was planned by Fox & allowed me to run sag and still have near 120mm travel.

Lots of forks don’t bottom out very close to the CSU. Measuring the length of exposed stanchion doesn’t tell you anything…..air down the fork, bottom it, air it back up and then measure to where the o-ring stopped.

Fox forks have a tall bottom out bumper. If you compress the fork all the way...you'll see that it stops some 10mm before the CSU.

On the Factory forks...full travel be right at the top of the K0ckshima logo,

Huh. I thought it was so you could install a 130mm air shaft and increase travel to 130.
I learn something new every day.
