This is a great, smooth fork. It is a little bit of a challenge to set up, but there are several YouTube videos available. I would certainly buy it again.
I’m very happy with this inverted fork that Biktrix installed on my Ultra XD. Once you pump up the upper chamber you can tell the sag from sitting on it. Then add about 10 pounds to the bottom section or what feels right. It has a rebound wheel on the right side that’s very accessible. It’s seems infinitely adjustable to the rider and terrain. I’m still learning but already I know it’s for me. It’s pricey but very well built and management is very responsible with questions.
Yes! Thanks! Nice addition to bike. My first front suspension bike so it feels stable and cushions like I was hoping!
