Helix Race GR chainrings are gravity optimized direct mount chainrings designed to withstand the punishment of downhill, bikepark, and freeride disciplines. They’re crafted of AL-7075-T6, and highly CNC optimized for minimal weight penalty, and great looks. Paired with Helix Race GR Cranks, -7mm offset GR chainrings produce a 56.5mm chainline suitable for most long-travel bike geometries. Featuring e*thirteen’s M4 narrow-wide tooth profile, they deliver improved chain retention, reduced noise and system wear, and seamless compatibility with both Shimano and SRAM drivetrains, (including T-type).

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.
Specialized SWorks SL8 light and fast. Sierra Bike Supply was helpful and responsive. Recommended online store.

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.
