Mach 4 SL V4 XT Di2 with Fox Performance suspension and Shimano electronic shifting
What Our Gearhead® Experts Are Saying:
"Shimano XT Di2 delivers incredibly precise shifts with minimal effort, and paired with Pivot’s dw-link platform it creates a very efficient race setup. The Fox Performance suspension feels supportive under power and controlled through chatter. It’s a smart choice for riders who want dependable electronic shifting and race-focused performance without stepping into top-tier pricing."
The Mach 4 SL V4 XT Di2 Mountain Bike pairs Pivot’s advanced hollow-core carbon construction with Shimano’s proven electronic shifting technology for a refined cross-country race experience. The dw-link rear suspension provides 100mm of efficient travel that maintains traction under hard efforts while preserving crisp acceleration. Up front, the Fox Performance 34 SL fork delivers 120mm of controlled travel, enhancing confidence on modern XC courses that demand both speed and technical capability.
Shimano’s XT Di2 M8200 12-speed drivetrain features electronic precision and a wide 10-51t cassette range, ensuring smooth gear changes across steep climbs and fast descents. The Shimano XT 2-piston brake system with 180mm front and 160mm rear rotors provides reliable stopping performance. DT Swiss X1900 wheels in a Boost configuration increase stiffness and durability, while Maxxis Rekon Race 29 x 2.4in tires balance low rolling resistance with dependable cornering grip.
For competitive riders and performance-driven trail enthusiasts alike, the Mach 4 SL V4 XT Di2 offers a lightweight, efficient, and technologically advanced platform built to excel on race day and beyond.
