Megatower C Eagle 90 Mountain Bike

What Our Gearhead® Experts Are Saying:

"I built out a Megatower C 29 90 for my race season and haven’t looked back. It climbs surprisingly well for how burly it is, and on descents, it’s just in a different class—quiet, fast, and composed. It’s made to go fast, and everything about this build backs that up."

The Megatower C 29 90 Mountain Bike is a no-compromise enduro rig built for riders who live for high-speed descents, brutal transfers, and the raw edge of racing. It delivers 170mm of rear travel via Santa Cruz’s refined VPP™ suspension platform, offering an aggressive combination of efficiency and downhill composure. The geometry is long, low, and slack, with a full 29-inch wheel setup for rollover speed and stability on technical terrain.

The FOX 38 Float Performance fork provides a stiff chassis for steering precision through blown-out turns and rock slabs, while the Float X rear shock brings mid-stroke support and consistent traction over rough surfaces. The drivetrain is built around SRAM’s T-Type 12-speed system, including the XS 1275 cassette, 90 crankset, and Flattop GX chain—all working seamlessly even under max effort.

Reserve 30|TR and 30|HD alloy wheels round out the build with DT Swiss 370 hubs, offering high-end strength and reliability. Maxxis Minion tires—with EXO+ up front and Double Down casing in the rear—hold tight in all conditions. With a OneUp cockpit and dropper post, SRAM Maven Base brakes, and full-frame protection built in, the Megatower C 29 90 is ready for enduro race day or backcountry missions that never let up.

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 Gearheads are always here to help.
