What Our Gearhead(R) Experts Are Saying:"I notice the Mach 4 SL feels instantly responsive the moment power hits the pedals. The DW-Link platform stays remarkably neutral when climbing, and the frame stiffness translates directly into forward momentum. The T-Type Transmission is a standout-it shifts smoothly even when I'm pushing hard, which is exactly what I want on race day."When the pace is high and the course is unforgiving, we want a bike that feels sharp, composed, and fast from start to finish. The Mach 4 SL thrives in that environment, delivering a lively ride that encourages us to attack climbs, carve through corners, and stay aggressive deep into the final lap. It's built for riders who measure success in seconds saved and lines perfected. At the core of the Mach 4 SL is Pivot's size-specific carbon frame paired with an XC-optimized DW-Link suspension. Adjustable rear travel allows us to fine-tune the bike for everything from explosive short-track races to longer marathon efforts, while modern geometry and thoughtful frame details keep the ride focused, efficient, and confidence-inspiring. 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.
