The Mach 4 SL is XC, distilled to its fastest form—engineered for efficiency, sharpened for precision and built to master the modern racecourse. Born from the crucible of World Cup XC and epic endurance racing, it balances a feathery build with an obsession for stiffness, control and efficiency. This is Pivot’s sharpest tool for riders who live in the red zone, engineered to crush climbs and meet the intense demands of real trails where races are actually won.

The Mach 4 SL carries the legacy of Pivot's very first bike, the Mach 4 Alloy, introduced in 2007. That original design set the foundation for Pivot's obsession with efficiency, suspension performance and race-bred handling. Since its debut in 2019, the Mach 4 SL has defined what a modern XC bike can be: lightweight, capable and relentlessly fast. Each generation refines that vision, evolving with the demands of today's courses while staying true to the speed and precision that started it all.

FEATURES:

  • Proprietary Ride Tuning Approach: At Pivot, every frame size is engineered independently through detailed strength-to-weight analysis and custom carbon layups. This process ensures that a size small rides with the same balance and performance as an XL, no shortcuts. By tuning stiffness and compliance uniquely for each frame, every rider gets the same confident handling, efficiency, and responsiveness, regardless of size. This approach is what allows the Mach 4 SL to feel so dialed, no matter who’s riding it. The Mach 4 SL also has the highest stiffness to weight ratio of any bike in our lineup because every gram matters and maximizing every watt of energy is critical.

  • Why dw-link?: dw-link is more than a suspension design; it’s the foundation of every Pivot. By combining precise anti-squat with exceptional small-bump sensitivity, it delivers a ride that pedals efficiently while staying planted and predictable. On the Mach 4 SL, that balance means every watt of your effort translates directly to forward momentum, with traction locked in across roots, rocks and technical climbs. The result is efficiency on the ups, composure in the corners and suspension performance that works with you on every section of trail.

  • Adjustable Travel: With our XC adapted travel-adjustable flip-chip you can choose between two rear travel options: 110mm and 120mm. The XC adapted travel-adjustable flip-chip lets riders fine-tune the Mach 4 SL’s rear travel for their terrain and riding style.

  • In-Frame Storage: The Pivot Toolshed™ in-frame storage system keeps your essentials securely tucked away, reducing clutter and providing quick, easy access for all your trail adventures, from short rides to longer excursions. The Toolshed™ includes two Toolshed™ bags, designed to carry a spare inner tube, essential tools and even a bit of extra space for a snack. An integrated magnet on the inside of the door holds quick links for fast and easy access.

  • Ultra-Clean Cockpit and Cable Routing: The Mach 4 SL’s cockpit is sleek and clutter-free with wireless shifting (Team/Pro/Expert builds) and Pivot’s Phoenix Team Flat carbon bars. The new dual cable port system simplifies routing and improves serviceability.

Size up
Size: Small, Color: Black
Overall a good hoodie. Thin-ish to medium weight, but don’t expect heavy weight. It’s soft but of course since it’s on more on the thin side it loses its softness quick but for the price it’s good. It’s good to cricut heat transfer on.

Love these!!!
Special Size: 7" Inseam without Pockets, Size: Large, Color: Ocean Blue
Super happy with these shorts!!! Wore them on a full day at the theme park. Stayed in place and did not ride up. No pinching or constricting. The material is buttery soft and the blue is so vibrant and pretty!! Don’t show every bump and imperfection, but does show some. It’s not totally smoothing. Very work out friendly, heat friendly, running errands friendly. Would definitely recommend and plan to buy other colors. Comfy waist band as well.

Excellent Work-out & Biking Short
Special Size: 7" Inseam without Pockets, Size: Small, Color: Ocean Blue
I love these biker shorts. They have just the right amount of lycra and they are super soft. They are true to size, and they fit perfectly on my 5'2", 125-pound frame. I purchased them for use in bike riding, and I am very pleased with the fit and stretch. The inseam length is perfect for bike riding, and the legs don't ride up my thigh. The only con to all the pros is there isn't a phone pocket. I ride my bike around town, and I would have liked to have a pocket for my phone when going inside a store. These shorts are well worth the price. I purchased three different colors and love them all. I would definitely purchase this item again.
