Santa Cruz Bicycles Bronson C Eagle 70 Mountain Bike

Push the pace with the Bronson C MX 70—built for speed, traction, and playful precision

What Our Gearhead® Experts Are Saying:

"I’ve ridden the Bronson C MX 70 through everything from steep tech to high-speed jump trails, and it’s a dream. The mixed wheel setup gives it that nimble, flickable rear with a planted front end, and the 150mm rear/160mm front travel balance eats up chunk. SRAM’s T-Type drivetrain shifts flawlessly even under load, and those Reserve alloy wheels with Fillmore valves? Chef’s kiss."

We throw a leg over the Bronson C MX 70 when we’re chasing after big-mountain flow and loose, techy corners. Santa Cruz´s proven VPP™ suspension platform paired with the MX (mullet) wheel configuration delivers an unreal blend of rollover and agility that feels tailor-made for park laps, shuttle days, and full-send descents.

This kit comes locked and loaded with SRAM´s latest T-Type 12-speed drivetrain, offering rock-solid performance and in-ride shifting confidence. The FOX Float Rhythm rear shock and RockShox Lyrik fork deliver plush suspension feel and big-hit capability. Paired with Maxxis EXO+ tires, Reserve 30|TR AL wheels, and stout SRAM DB8 brakes, this is a complete trail weapon ready for high-speed chaos or long technical rides.

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.
