Meet the 5DEV Titanium Mountain Cranks — 5-axis-machined performance for riders who demand strength, lightness, and rock-solid reliability. Built from solid Ti-6Al-4V bar stock on 5-axis CNC machines in San Diego, these cranks blend aerospace-grade metallurgy with race-ready design. The result: a stiff, confidence-inspiring platform that survives harder lines and keeps your power transfer honest when the trail gets rowdy. Made for riders who push limits and expect gear that keeps up. If you want cranks that feel like an upgrade at first pedal stroke and still look factory-fresh after a season of abuse, the 5DEV Titanium Mountain Cranks are your ticket to faster laps and stiffer confidence. PLEASE NOTE: Crank spindles are sold separately to accommodate specific individual size requirements (Cranks are only compatible with 5DEV spindles).

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.
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.

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.
