Fox Rhythm 36 fork for 29" mountain bikes. It's in good shape with a working lockout (Grip damper). Boost spacing works with a 15x110mm through axle hub. Tapered steer tube measures about 8 1/4".
A few weird things about this fork, which I bought in a lot of bike parts and have never ridden:
Travel is super long, around 190mm of exposed stanchion tube. That and the fact it's missing the 4-digit Fox ID sticker makes me think someone replaced the airshaft with a really long travel one. It also has not one but two stanchion o-rings for judging sag, a phillips screw in the brake hose clamp, and the star nut driven too far down the steer tube (this is an easy fix).
Includes thru-axle and cap to protect rebound dial.
I can deliver anywhere in the greater Tucson area for just $20!
