Lightweight 29-inch aluminum wheelset for cross-country and trail riding, featuring innovative Twinpair spoke technology, 23 mm internal width, and Shimano HG freehub - includes tubeless valves.

The Crankbrothers Cobalt 2 XC wheelset combines an exceptional design with high stability, direct power transfer, and a low moment of inertia. Designed for sporty cross-country and trail riding, it offers a balanced combination of acceleration, stiffness, and reliability.

The distinctive Twinpair spoke design clearly sets the Cobalt 2 apart from classic wheelsets. The paired spokes form stable triangular structures that support high stiffness and even force distribution. At the same time, the special design allows individual spokes to be replaced without removing the tire.

The high-quality 6061-T6 aluminum rims with a 23 mm internal width provide a stable base for modern MTB tires. Thanks to the closed rim bed with no through spoke holes, the wheelset is ready for tubeless use. No additional tubeless rim tape is required.

The robust Crankbrothers aluminum hubs are equipped with a reliable freehub system. The rear features a steel Shimano HG freehub body with 3 pawls and 21 ratchet teeth. The wheelset is designed for classic non-Boost MTB frames with a 15x100 mm thru axle up front and 12x142 mm at the rear.

Highlights:

• Twinpair spoke technology: unique paired spoke arrangement for high stability and stiffness.
• 23 mm internal width: wide aluminum rims for good tire support, traction, and control.
• Tubeless Ready: closed rim bed without spoke holes - no additional tubeless rim tape required.
• Low moment of inertia: optimized weight distribution for direct acceleration and braking response.
• Shimano HG freehub: durable steel freehub with 3 pawls and 21 engagement points.
• Non-Boost version: suitable for 15x100 mm front and 12x142 mm rear.
• Easy-to-maintain design: uniform spoke length and spoke replacement without removing the tire.
