The Crank Brothers Cobalt 1 650b/27.5" mountain biking wheels are a value-packed, entry-level aluminium wheelset that's perfect for cross country and trail riding.
These wheels are stunning both visually and on the trails due to Crank Brothers' unique design that's based on principles of strength, stiffness, and acceleration - exactly what every mountain biker seeks out. The Cobalt 1 wheels feature Twinpair spoke technology which pairs 2 sets of 12 spokes (so 24 spokes/wheel front and rear) to maximize strength and stiffness.
They're incredibly user-friendly, too, as there's only one spoke length for all the spokes both front and rear. The 6061-T6 anodized aluminium rims plus the Cobalt 6061-T6 hubs are the epitome of strength, reliability, plus smooth-rolling performance thanks to sealed cartridge bearings.
- Simple and beautiful - crankbrothers unique wheel design is based around principles of strength, stiffness, and acceleration.
- Low rotational inertia - unique wheel design distributes mass closer to the hub for faster acceleration and deceleration.
- Twin pair spoke technology - designed using the strongest shape in construction, the triangle, to maximize strength and stiffness.
- Single spoke length - easy to true and replaceable without removing the tyre.
