Campagnolo Shamal Carbon C21 Disc 2-Way Fit Wheelset

The Campagnolo Shamal Carbon C21 Disc 2-Way Fit Wheelset carries one of Campagnolo's most recognized wheel names — the Shamal, first introduced in 1992 as a professional-level lightweight road wheel — into carbon construction for disc brake bikes. The C21 is an all-road disc wheelset with a 21mm internal rim width, 2-Way Fit tubeless and clincher compatibility, Campagnolo's G3 spoke grouping, and cup-and-cone bearings that can be serviced rather than replaced. At 1,585g per pair, it's a composed choice for road and endurance riders who want Italian engineering and long-term reliability without reaching into the top of the Campagnolo lineup.

One of the most deliberate design choices on the Shamal C21 is the differentiated rim depth: 35mm at the front, 40mm at the rear. That asymmetry is intentional. The deeper rear rim adds stiffness and aerodynamic efficiency where power input is highest — sprinting, hard accelerations, sustained efforts out of the saddle. The shallower front rim reduces steering inertia and improves handling predictability at speed and in crosswind conditions. The result is a wheelset where each wheel is tuned to what its position on the bike actually demands. For riders who spend time at speed on rolling or flat terrain, that differentiated depth is a meaningful engineering choice, not a cosmetic variation between trim levels.

G3 Spoke Pattern and Hub Design

The carbon rims are laced using Campagnolo's G3 spoke system — three spokes grouped together on each side of the hub, alternating around the circumference rather than spaced uniformly. Campagnolo's intent with G3 is more balanced spoke tension distribution and improved lateral stiffness, which produces more consistent tension across the spoke bed under the asymmetric loads that disc braking introduces. When the caliper applies force, it creates a twisting moment the wheel must absorb without deflection; the G3 grouping addresses that directly. Each wheel uses 24 slim steel spokes and an aluminum monolithic hub body finished in black. The front hub runs a 12x100mm thru-axle; the rear runs 12x142mm.

Cup-and-Cone Bearings and 2-Way Fit Tubeless

Campagnolo uses cup-and-cone bearings in the Shamal C21 rather than sealed cartridge units. This is Campagnolo's long-standing design preference, and it remains functionally relevant: the bearings are adjustable for play, serviceable in a shop or in the field, and when maintained properly, can outlast cartridge bearings at a fraction of the replacement cost over a long ownership period. The bearings generate momentum quickly and sustain rolling speed efficiently — a quality that's apparent over a range of surfaces and under sustained load. The 2-Way Fit rim design accepts both tubeless and standard clincher tires from the same rim bed. The tubeless channel is built without a liner and without seams or joins, which removes the leak points that complicate setup on other tubeless systems. The 21mm internal rim width comfortably accommodates tires from 25mm through to wider all-road sizes up to 50mm.

The Shamal C21 Disc is available with three freehub configurations: Campagnolo N3W for Campagnolo 12-speed drivetrains, Shimano HG for Shimano and SRAM 11-speed, and SRAM XDR for SRAM 12-speed AXS. Price ranges from $1,739 to $1,750 depending on freehub selection. The Shamal name has represented the same combination of accessible performance and Italian build quality since 1992. The C21 Disc updates that positioning for modern disc brake bikes with carbon construction and tubeless capability — without abandoning the serviceability that makes Campagnolo wheels a long-term investment rather than a consumable.
