Bronson 5 C GX AXS. When you can only have one bike and your mission is to ride that bike into the ground, this mixed-wheel Bronson is built to handle everything from bike-park laps to blown-out loamers and backyard jump lines.
Key highlights
- 150 mm rear / 160 mm front travel Carbon C MX VPP™ frame tuned for aggressive all-mountain and enduro riding.
- MX wheel setup (29" front / 27.5" rear) blends rollover confidence with quick, playful handling.
- RaceFace ARC 30 or Reserve 30|SL alloy rims laced to DT Swiss 370 hubs for a strong, serviceable wheelset.
- Maxxis Assegai / Minion DHR II tires in 3C MaxxGrip / MaxxTerra EXO+ casings for dependable grip and braking traction.
Suspension and braking
- FOX 36 Float Performance Elite, Grip X2, 160 mm fork keeps the front wheel glued to the ground when trails get steep and rough.
- FOX Float X Performance Elite rear shock offers a supportive mid-stroke with controlled bottom-out for hard-charging riders.
- VPP™ rear suspension layout balances sensitivity, mid-stroke support, and pop for playful yet composed handling.
- SRAM Maven Bronze 4-piston brakes with HS2 200 mm rotors deliver powerful, consistent stopping on long descents.
Drivetrain and cockpit
- SRAM GX Eagle AXS Transmission wireless 12-speed drivetrain with a 10–52 t cassette for big climbs and fast descents.
- SRAM GX Eagle DUB T-Type crankset with 32 t chainring and 170 mm arms on all sizes keeps things simple and durable.
- Santa Cruz carbon handlebar and OneUp Enduro stem create a precise, confidence-inspiring cockpit.
- OneUp dropper post, SDG Bel-Air V3 saddle, and Santa Cruz house grips round out a ready-to-ride package built for long days on the hill.
Fit, setup, and recommended upgrades
- We want every rider, local or remote, to get the best performance from their new Bronson 5 C GX AXS.
- Local pickup customers: We can set suspension sag, rebound, and tire pressures so the bike is tuned correctly for your weight and local terrain.
- Shipped bikes: The bike arrives professionally assembled and test ridden. If you need help with suspension or cockpit setup at home, our staff can walk you through the basics or answer questions before your first ride.
- Recommended upgrades: Many riders choose to add pedals, body protection, or cockpit adjustments (grips, bar width, stem length) to match their riding style. If you would like suggestions, we can help you choose options that complement the Bronson’s geometry and intended use.
