| Merchant: Nashbar Crank Brothers Cobalt 3 27.5 Mountain Wheelset. The Crank Brothers Cobalt 3 27.5 mountain wheels are an elite-level aluminum wheelset that's perfect for high performance 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 the discerning, demanding mountain biker seeks out. The Cobalt 3 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 plus the spokes can be replaced without removing the tire. The 6061-T6 anodized aluminum rims are the epitome of strength and light weight, and since they don't have any holes rim strips aren't necessary and tubeless conversion is very straightforward. The Cobalt 6061-T6 hubs are legendary performers renowned for strength, reliability, plus smooth-rolling performance thanks to sealed cartridge bearings.
