CONCEPT SPEED 29" MTB Carbon Race Rim

340g of carbon, built for riders who know exactly what they want. Bring your own hub, choose your spokes, and build the XC or trail wheel that fits your riding, your weight, and your terrain. The Concept Speed Carbon Race Rim gives you a serious foundation without locking you into someone else's complete wheel spec. 

A custom wheel is only as good as the rim it starts with. Pick the wrong one and you are chasing trueness for the next two seasons. Pick this one and you get 340g of precisely laid carbon with a published tension spec, a hookless tubeless profile that works, and the flexibility to run 28H or 32H depending on how hard you ride.

The hookless bead is tubeless only. That is not a limitation, it is the point. Lower pressures. More traction. A tyre that grips the trail instead of pinballing off it. The 30mm internal width supports 2.3 to 2.6-inch tyres at up to 3 bar (44 psi) and seats them consistently. No wrestling with the bead, no pressure spikes, no surprises mid-race.

Intermediate-modulus fibre for toughness and impact resistance. High-modulus fibre where the layup demands stiffness and minimum weight. No system weight limit. Five-year manufacturer warranty, 3-year Crash Replacement Warranty at 50% of the current retail price, The Trust Guarantee (register within 30 days of purchase at conceptspeed.co.za/register). The rim earns its place on its spec. The support earns it again.
