Came stock on my megatower arc 30 alloy, I've had a couple moments where i thought i completely destroyed my wheel (2 meter huck to negative at speed) cased a 50 foot step down pretty bad and these wheels haven't gave way yet where they would have on any other rim I've had. props raceface

doesnt look bad but listen to the sound

If you're a big or powerful rider not looking to drop ~ $1k or more on a carbon rim setup look no further. I threw these on the megatower in place of the oem AR 30, and it feels like a new bike in the best way possible! More control, more pop, and more confidence. The bike rides like it should now. Definite improvement in wheel tracking through berms; I can really throw my weight around with the stiffness of the arc 30'HD, and can better feel the trail beneath me.
Can't comment on the durability yet, but I dont have any concerns. If you want to make your 29er stiffer and more sensitive you cant go wrong...

These rims are amazing! As a 250lb rider in the Texas rocky hill country, a year later they are still like new and spin perfectly straight.

I've been running ARC 30 HD's on my downhill bike for a while now. I bought to fresh hoops and I just love how reliable and tough these wheels are. And how can you go wrong with the warranty?

Came quick, easy tracking and love the way it looks and handles
