Warranty replacement hub
Chromag is awesome. Had an issue with my hub just a couple months before the warranty expired and they replaced it and shipped it out to the east coast for me. I love this bike company!

XD for me!
This new XD driver was so easy to install now I can run my upgraded drive train, smooth and quiet just how I like it.

This free hub is sooooo good.
Such a satisfying noise from this free hub. Sure it does have the crazy .5° between engagement points as say an I9 hub… instead it’s exceptional value and real strength and reliability. Love it. And the sound… so good.
