Santa Cruz Bicycles Bronson C Eagle 90 Mountain Bike

Crush corners and technical trail with the Bronson C MX 90—VPP™ control and T-Type shifting

What Our Gearhead® Experts Are Saying:

"I upgraded to the Bronson C MX 90 for the FOX Float X Performance shock and DT Swiss hubs, and I’m stoked on the bump sensitivity and precision this setup brings. The 150mm rear travel gives just enough squish without wallowing, and with the SRAM 90 Eagle T-Type drivetrain, I’m hitting shifts mid-sprint without skipping a beat."

The Bronson C MX 90 hits that sweet spot between all-mountain party machine and enduro-capable workhorse. Santa Cruz´s refined VPP™ suspension keeps the bike calm and composed in chunder while the MX (mullet) wheel setup boosts playfulness and front-end confidence. From high-speed jump lines to backcountry rock gardens, this build is ready to flow.

This C-series carbon frame is paired with a FOX 36 Float fork and Float X shock, giving 160mm up front and 150mm in the rear for balanced capability. SRAM’s T-Type drivetrain brings crisp, seamless shifting across a wide 10–52t range, even under load. Maxxis EXO+ rubber holds its own in the gnar, while DT Swiss 370 hubs and Reserve 30|TR AL rims provide a solid, responsive ride feel. With a OneUp cockpit and dropper post, this ride is dialed from the start.

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.
