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

Big terrain, mixed wheels, and enduro muscle—Firebird Pro X0 Eagle Transmission delivers

What Our Gearhead® Experts Are Saying:

"I’ve been riding this exact Firebird Pro X0 MX build with the Reynold Blacklabel wheels, and it’s next level. The carbon setup is insanely responsive—super light, incredibly stiff, and tracks like a dream when charging through rough terrain. With the mixed-wheel 29/27.5 setup, it feels both fast and nimble, especially in tight, technical sections. It’s one of the most confident, capable bikes I’ve ever ridden—an absolute enduro weapon."

When we´re chasing gravity and pushing limits, we want a bike that’s both razor-sharp and brutally tough—and the Firebird Pro X0 Eagle Transmission MX with Reynolds Blacklabel wheels delivers. This mixed-wheel enduro machine combines Pivot’s long-travel carbon chassis with top-tier drivetrain tech and a dialed geometry made for steep lines, big hits, and rowdy backcountry trails. The mullet setup keeps us stable up front with a 29-inch wheel and snappy out back with a 27.5-inch rear, giving us the best of both worlds for descending confidence and cornering control.

The Reynolds Blacklabel Enduro Pro carbon wheels bring a lightweight, high-performance feel to this build. Paired with SRAM’s wireless X0 Eagle Transmission, shifting stays tight even under heavy load. Fox handles suspension duties with a Factory 38 fork and Float X2 rear shock for a buttery, bottomless ride that stays composed at speed. Finished with SRAM Maven brakes, a size-specific Fox Transfer dropper, and Pivot’s carbon cockpit, this Firebird is built to push hard and go fast—no questions asked.
