What Our Gearhead® Experts Are Saying:"I’ve been riding the Firebird Pro X0 in the full MX setup with carbon wheels, and it’s insanely capable. That 29-inch front plows over everything, while the 27. 5 rear lets it snap through tight corners. The carbon Reynolds wheels add a precise, poppy feel on the trail—and with the X0 Transmission, it's basically a mini DH bike with climb mode."When the trail gets steep, rowdy, and fast, we want a bike that feels limitless. The Firebird Pro X0 Eagle Transmission MX with carbon wheels is built exactly for that—a mullet-wheeled, long-travel machine engineered to thrive on big terrain. This build features a 29-inch front wheel for rollover and confidence, paired with a 27. 5-inch rear wheel that gives it a playful edge in tight switchbacks and jumps. Add in carbon Reynolds Blacklabel Enduro Pro wheels with Industry Nine hubs, and this Firebird gains a whole new level of responsiveness and speed. It’s backed by SRAM’s X0 Eagle Transmission—a wireless drivetrain that delivers instantaneous, precise shifting under full load. Fox Factory suspension handles the hits with a 170mm GRIP X2 fork and a Float X2 shock out back, giving us unmatched traction and control. SRAM Maven Silver brakes deliver all the stopping power we need, while Pivot’s carbon cockpit and size-specific geometry keep things balanced when we’re pushing limits. This bike is for riders who live for descent-driven rides but still need to earn their turns.
