Rocky Mountain Element C70 GX Transmission—carbon XC geometry with wireless Eagle drivetrain
What Our Gearhead® Experts Are Saying:
"Wireless Eagle Transmission means I'm never thinking about cable tension mid-ride—the shift is there when I want it, every time. Plus, the AXS Pod keeps the cockpit clean. The Fox Performance Elite suspension runs front and rear without mixing damper families, so the feel stays consistent from the first hit to the bottom of the descent."
Smoothwall carbon frame and Smoothlink SL suspension
The full carbon frame and rear triangle use Rocky Mountain's Smoothwall process, with the Smoothlink SL flexstay delivering 120mm of rear travel through a design that mimics the progression and feel of a four-bar linkage without the added pivot hardware. Rocky Mountain runs size-specific shock tunes on the Fox Float Performance Elite, so the spring rate and progression are calibrated per frame size rather than split into two or three weight categories. The RIDE-4 chip adjusts head angle and BB height across four positions.
Fox 34 Float Performance Elite with GRIP X damper
The 34 Float Performance Elite runs 130mm with Fox's GRIP X damper, giving us a mid-travel fork with enough chassis stiffness for aggressive XC geometry without the weight penalty of the 36 platform. External high and low speed compression and rebound adjustment give precise tuning for terrain and rider weight.
SRAM GX Eagle Transmission wireless
GX Eagle Transmission runs the full wireless AXS ecosystem at a price below comparable builds. The UDH-mount derailleur eliminates the replaceable hanger and the alignment issues that come with it. At the cassette, the 10-52T range pairs with a 32T chainring for a 1x spread that covers technical climbing and descending without a bailout gear compromise. The AXS Pod controller mounts to the bar clamp rather than the shifter body, keeping the cockpit clean.
Heads up! We do our best to keep bike specs and images current, but occasional component changes can happen without warning, and sometimes the photos might not show the exact build you'll receive. If you want to double-check the details, our Gearhead® Experts are always here to help.
