Helix Race Carbon Cranks are a milestone in carbon crank design. Featuring highly optimized carbon crank arms and lightweight 30mm aluminum spindle, these cranks dramatically reduce weight while maintaining incredible strength. Weighing in at just 335g (170mm), they exceed ASTM 4 test standards, making them equally at home on everything from Aggressive Trail and All Mountain rigs to feather-weight XC Race builds. The Helix Race Carbon utilizes an 8-bolt chainring interface (chainring sold separately), with a twist. By incorporating a unique four-bolt locking mechanism in their Helix Race 8-Bolt Chainring interface, weight is further reduced while improving longevity (standard 8-bolt chainrings also compatible). Available in popular crank lengths of 165mm, 170mm, and 175mm, Helix Race Carbon cranks come equipped with molded crank boots, an APS adjuster, captive pedal washers, and a convenient self-extractor system, ensuring simple installation and maintenance. If you're looking for the highest strength-to-weight ratio in MTB cranks, you just found it!

Everything was great. Was waiting for the SL9 to release since the first leak. Going from a SL7 was night and day.
Also Sierra Bicycle Supply, was amazing. Will be shopping here plenty more. The service they displayed was top tier, from the order placing online all the way to the delivery.

Literally EPIC
Fast shipping and perfect frame set as described. It's literally the lightest built MTB I've ever felt. My wife will be smashing on it at this year at the Leadville 100. LFG Thanks guys!

Exceptional Wheels
The CLX III are exceptional I was a little apprehensive about buying them having ridden the Enve 4.5 but you feel less crosswinds and their lighter and spin fast. The spokes seemed to offer a lot of dampening vibration. Win win in my book.

After many years I wore out my derailleur gears. Since I ride on my wind trainer daily, I needed to get up and riding again. Riding us part of my cancer therapy. Replacing the gears was a quick and easy way to fix the problem. Cost was fine and the delivery was fast. Thank you.
Got this for my kids bike. He does XC racing. Has been riding in dry lose dirt, wet conditions. Lots of climbing and some downhill. He loves them. Shipped fast and in sexure packaging. I would definitely buy again.
Heard a lot of good things about this tires put them on my commuter. The roll much faster than the schwable energizers on it. Puncture protection only time will tell.
