Firebird Pro X0 T-Type Neo MX SE Carbon Wheel Mountain Bike

What Our Gearhead® Experts Are Saying:

"This is probably the best carbon wheel setup I’ve ever ridden. The Reynolds Blacklabel are light, stiff, and feel super fast through tight corners. With the 29/27.5 mix, the Firebird Pro X0 just charges through tech but stays playful when you need it to. And the SRAM X0 Transmission is just icing on the cake—every shift is dead-on, even mid-sprint."

The 2025 Pivot Firebird Pro X0 Eagle Transmission MX with Reynolds Blacklabel wheels strikes a refined balance of precision, playfulness, and strength. This build is engineered for riders who demand high-end drivetrain performance and mixed-wheel agility. The Firebird’s MX layout—29-inch front and 27.5-inch rear—remains consistent across all sizes, offering confident front-end tracking and responsive handling at the rear.

Pivot’s carbon frame is paired with Fox Factory suspension for peak control in demanding terrain. The 170mm GRIP X2-equipped 38 fork and 165mm DHX Neo rear shock create a stable platform through rock gardens, jumps, and steeps. SRAM’s X0 Eagle Transmission brings next-gen wireless shifting to the build, offering unmatched consistency under power, with zero setup guesswork thanks to its direct-mount design.

The Reynolds Blacklabel Enduro Pro carbon wheels are a standout upgrade—engineered for strength-to-weight performance with a 30mm internal width to support modern enduro tires. Finished with SRAM Maven Silver brakes, HS2 rotors, and Pivot’s own carbon cockpit, this Firebird MX build is tuned to dominate race courses and destroy shuttle laps, without compromising pedal power on the climbs.
