Engineered for podium-level XC racing, the Mach 4 SL V4 Team XX T-Type Carbon Wheel Mountain Bike
What Our Gearhead® Experts Are Saying:
"The XX SL Transmission system is incredibly crisp and durable, especially under heavy pedaling loads. Combined with the Fox Factory suspension and carbon wheels, the bike feels light, precise, and ready for race pace efforts. It is a true high-end XC machine that rewards strong riders with immediate response."
The Mach 4 SL V4 Team XX T-Type Carbon Wheel Mountain Bike showcases Pivot’s premier cross-country race platform with a no-compromise component package. The hollow-core carbon frame is engineered around the dw-link suspension system, delivering 100mm of efficient rear travel that enhances traction while maintaining exceptional pedaling response. Up front, the Fox Factory 34 SL fork provides 120mm of controlled travel, ensuring confident handling on modern XC courses that blend speed and technical features.
SRAM’s XX SL Eagle Transmission drivetrain features a direct-mount rear derailleur design for increased durability and precise shifting under load. The 10-52t cassette offers broad gearing for steep climbs and high-speed descents, while the lightweight crankset maximizes power transfer. SRAM Motive Ultimate 4-piston brakes paired with CenterLine rotors deliver consistent stopping performance in race conditions.
Reynolds Blacklabel 309/289 XC carbon wheels reduce rotational mass and improve stiffness for rapid acceleration and accurate tracking. Combined with Maxxis Rekon Race 29 x 2.4in tires, the bike achieves an ideal balance of low rolling resistance and cornering confidence. For dedicated XC racers and performance-focused riders, this build represents a refined, lightweight, and podium-ready package built to perform at the highest level.
