Cannondale SuperX LAB71 A/M frame set Moonrock

Description

The Cannondale SuperX LAB71 A/M Moonrock frameset is a race-focused gravel frameset designed for building a lightweight, aerodynamically optimized custom bike. It sits in the top performance tier of framesets, where the balance of stiffness, weight, and integrated routing is tuned for modern gravel racing as well as fast riding on rough asphalt.

Frame and geometry

At its core is a carbon composite frame using Series 0 carbon construction, complemented by Proportional Response construction—meaning the layup and tube dimensions are tuned by frame size to deliver consistent stiffness and compliance across the size range. The OutFront geometry concept targets stability at higher speeds while maintaining precise tracking, which is key for gravel with wider tires. Up front, it uses a Delta steering column and an integrated headset with a tapered 1-1/8" – 1.5" size, making clean internal routing of hoses and cables easier. The frame is compatible with a BSA 68 mm threaded bottom bracket, and the rear axle is a 12×142 mm thru-axle; available sizes: 46, 51, 54, 56, 58, 61.

Components

This is a frameset, so it does not include a complete drivetrain or wheelset; the choice of shifting (mechanical vs. electronic, 1× or 2×) and cassette is up to the builder. The frame is set up for disc brakes with flat mount disc mounts; specific calipers and rotor sizes are not part of the frameset specification. Included is the Lab71 SuperX (Series 0) carbon fork with internal routing, an integrated crown race, a 12×100 mm thru-axle, and a 55 mm offset. The package also includes the headset and the Cannondale C1 Aero 27 Carbon “D”-profile seatpost; seatpost offset is 0 mm (size 46) and 20 mm (sizes 51–61). The cockpit can be built with the integrated SystemBar R-One combo or with a stem compatible with 1-1/8" (depending on the routing solution around the head tube).

Ride characteristics

Series 0 construction combined with Proportional Response aims for high torsional stiffness under power and consistent cornering behavior across sizes, which matters at race pace on gravel as well as on paved transitions. OutFront geometry together with the 55 mm fork offset supports stability on descents and rough surfaces without making the bike feel twitchy during quick line corrections. The “D”-shaped carbon seatpost adds vertical compliance at the saddle, which is one of the main sources of comfort on a stiff (non-suspended) gravel frame without compromising pedaling efficiency.

Who it’s for

This frameset is intended for experienced riders and racers who want to build a gravel bike with an emphasis on low weight, aerodynamic integration, and clean internal routing. Compared to standard carbon gravel frames, it targets riders who care about compatibility details (BSA, flat mount, thru-axles, UDH) and prefer a build tailored precisely to their own drivetrain, wheels, and cockpit.
