SuperX 4 AXS

The SuperX lineup spans five builds, split primarily by frame material and electronic drivetrain tiers. The flagship LAB71 model uses a lighter, premium carbon layup to shed frame weight. It comes equipped with a SRAM Red XPLR AXS 13-speed groupset, an integrated power meter, a CeramicSpeed bottom bracket, and a one-piece carbon cockpit.

The rest of the range uses the standard carbon frame. The 1 build steps down to SRAM Force XPLR AXS, retaining a power meter and the one-piece carbon bar, while rolling on deep-section DT Swiss carbon wheels. The 2 build shifts to a Shimano GRX 825 Di2 2x12 drivetrain, offering tighter gear jumps for riders who prefer a traditional double chainring, paired with Reserve carbon wheels and a two-piece alloy cockpit.

For more accessible price points, the 3 and 4 AXS builds utilize SRAM's 13-speed Rival XPLR and 12-speed Apex AXS groupsets, respectively. Both feature the two-piece alloy cockpit and move to DT Swiss alloy wheelsets. Across the entire range, Cannondale specs 40mm Vittoria tires, leaving ample room for riders to utilize the frame's generous clearance if they prefer higher-volume rubber.

Reviewers consistently note that the SuperX behaves much like a modern aerodynamic road bike that has been adapted for the dirt. The rigid chassis and aggressive posture translate power immediately, making the bike highly responsive under hard pedaling. Testers found that it "feels naturally efficient to ride on tarmac" (Cyclist Magazine), carrying speed effortlessly across smooth sectors and hardpack.

When the surface degrades, the frame relies heavily on its engineered flex zones and D-shaped seatpost to isolate the rider. While the front end communicates a fair amount of chatter through the handlebars, the rear triangle effectively smooths out the ride. One tester noted that the bike "feels as fast as a road bike while effectively absorbing rough terrain" (Bicycling).

Handling is generally described as stable and composed rather than overly twitchy, a trait that pays dividends on long, fatiguing race days. The steering remains predictable at speed, making it a "rock-solid choice for rough terrain and loose gravel" (Granfondo). However, several reviewers pointed out that the stock tires on some builds feel slightly narrow for the frame's capabilities, suggesting that riders pushing into technical terrain will benefit from sizing up the rubber to fully exploit the bike's descending composure.
