Mach 4 SL V4 Ride Eagle 70/90 with Fox Performance suspension and SRAM Transmission
What Our Gearhead® Experts Are Saying:
"I like how this build keeps the core performance of the Mach 4 SL platform while using the mechanical Eagle Transmission system. Shifting feels solid and reliable, and the Fox Performance suspension gives it that supportive, race-ready feel. It is a great option for riders who want modern drivetrain tech and proven suspension performance at a strong value."
Competitive Romantic Copy
The Mach 4 SL V4 Ride Eagle 70/90 Mountain Bike brings Pivot’s race-focused hollow-core carbon chassis together with SRAM’s Mechanical Eagle Transmission technology for a capable and efficient cross-country setup. The dw-link suspension system delivers 100mm of rear travel that maintains traction under power while preserving sharp acceleration. Up front, the Fox Performance 34 SL fork provides 120mm of controlled travel for modern XC courses that demand both speed and technical precision.
The SRAM Eagle 70/90 Mechanical Transmission 12-speed drivetrain features a direct-mount rear derailleur interface and a 10-52t cassette range for confident climbing and high-speed pedaling. SRAM DB8 Stealth 4-piston brakes paired with 180mm front and 160mm rear rotors deliver consistent stopping power. DT Swiss X1900 wheels in a Boost configuration enhance stiffness and durability, while Maxxis Ardent Race 29 x 2.2in tires balance rolling efficiency and predictable grip.
For competitive riders and ambitious trail enthusiasts, the Mach 4 SL V4 Ride Eagle 70/90 offers a lightweight, responsive, and performance-driven platform ready to tackle race courses and fast singletrack alike.
Heads up - We do our best to keep bike specs and images current, but occasional component changes can happen without warning-and sometimes the photos might not show the exact build you'll receive. If you want to double-check the details, our Gearheads are always here to help.
