What Our Gearhead® Experts Are Saying:
"This build feels incredibly fast the moment you put power down. The XX SL Transmission shifts instantly and handles torque without hesitation, and the Fox Factory suspension keeps the ride efficient while still tracking well in rough sections. The Reynolds carbon wheels spin up quickly and hold speed beautifully. If I were lining up for a high-level XC race, this is the kind of setup I would trust."
When we are chasing podium spots or lining up for a demanding XC course, the Mach 4 SL V4 Team XX T-Type Carbon Wheel Mountain Bike from Pivot delivers uncompromising race performance. Built around Pivot’s hollow-core carbon frame and dw-link suspension platform, it channels every watt into forward drive while staying composed through technical terrain. It feels explosive out of corners and razor sharp on steep, punchy climbs.
Fox Factory suspension pairs a 120mm Fox 34 SL fork with a Fox Factory Float rear shock delivering 100mm of highly efficient rear travel. SRAM’s XX SL Eagle Transmission drivetrain provides direct-mount precision and load-resistant shifting with a wide 10-52t range. Reynolds Blacklabel 309/289 XC carbon wheels reduce rotational weight for rapid acceleration and confident line choice, while Maxxis Rekon Race 29 x 2.4in tires balance rolling speed with dependable grip for modern race tracks.
