Pivot

Mach 4 SL Pro X0 Transmission Neo Mountain Bike

What Our Gearhead® Experts Are Saying:

"I notice how composed the Mach 4 SL feels at speed. The DW-Link keeps traction high without sacrificing acceleration, and the frame stiffness is exceptional when sprinting or climbing. The adjustable travel is a real advantage for racers dialing in their setup for different courses."

The Mach 4 SL is Pivot’s answer to modern cross-country racing, where efficiency alone isn’t enough. Built around an exceptionally stiff, size-specific carbon frame, it delivers immediate power transfer while maintaining control on increasingly technical XC tracks. The DW-Link suspension platform is tuned specifically for XC, staying firm under power yet opening up seamlessly when the trail turns rough.

This Pro X0 Eagle Transmission build highlights the Mach 4 SL’s race-first intent, pairing wireless drivetrain performance with a clean, modern frame layout. Adjustable rear travel allows riders to tailor the bike for short-track explosiveness or longer marathon-style events, while internal routing and molded frame protection keep things quiet and durable through a full season of racing.

From punchy climbs to high-speed descents, the Mach 4 SL is designed to carry speed efficiently and confidently. Whether lining up for a World Cup-style circuit or targeting long XC endurance rides, this bike is engineered to perform when every second matters.
