2026 SuperX 4 AXS Gravel Road Bike
Features
-
Rolling Fatties
Courses vary, terrain varies, weather varies. The SuperX fits tires up to 48mm for the frame and 51mm for the fork, with at least 4mm clearance on each side, ready for whatever tire the day demands.
-
D-Lightful
The D-shaped design of SuperX’s seatpost enhances aerodynamics and boosts vertical compliance, reducing muscle fatigue so you stay fresh and fast for the final sprint.
-
OutFront Geometry
OutFront pairs a slack head angle with a longer-than-normal 55mm fork offset, increasing stability and control on the steep and loose – while maintaining the snappy handling you need for quick line changes and last-second corrections.
-
Delta Steerer
The Delta Steerer design is great for gravel racing. It allows for clean cable integration from the cockpit into the frame, and a reduced frontal area for increased aero efficiency.
-
The Cover up
A slick cover hides SuperX’s top tube bag mount. It's there when you want it, invisible when you don’t.
All In to Go All Out
-
Fast & Light
Our KOM-winning road tech meets Unbound-winning engineering. SuperX is super aero and light to stay ahead of the pack in this rapidly -evolving era of high-speed, elbow-to-elbow gravel racing. With gravel race speeds averaging well over 35 km/h, SuperX brings a whole lotta free speed over any distance.
-
Gravel Glider, Not Grinder
SuperX’s sophisticated carbon construction smooths out the rough, floating above the gravel to keep you cranking. Specially constructed flex zones in the seat tube, rear triangle, and top tube work as a system with the D-shaped seatpost to absorb shock and vibration, keeping your mind and body fresher longer.
-
Handle It
Take the faster line. Pass on the inside. Lay off the brakes and let 'er fly. With its race-proven geometry, OutFront steering design, and finely calibrated frame stiffness, the SuperX’s handling blends stability and precision in a way that takes the drama out of clutch moments, letting you hold your line while staying on the gas.
-
Built to Take It. Tuned for You.
SuperX’s Proportional Response carbon construction is tailor made for gravel racing and for you. Fully customized by size, precisely oriented layers of different types and moduli of carbon fibers deliver an ideal balance of weight, stiffness and durability for every rider. All backed by our lifetime guarantee.
-
Get ‘Crossed Up
Is cyclocross your thing? SuperX has you covered. Throw on some 33c tires and hit it. With its straight-line speed, planted handling, and massive mud clearance, SuperX loves to battle it out between the tape. Oh, and the flat top tube is pretty nice on the shoulders too.

All In to Go All Out
