CONCEPT SPEED 29" Carbon Race Ultra Light Rim

You know the moment. The climb steepens, the gap opens, and everything that was manageable five minutes ago suddenly has to be earned. This is where rotating weight announces itself. At 290g per rim, the Concept Speed Carbon Ultralight Rim has almost nothing left to announce.

The rim is carbon, hookless, and tubeless only. Maximum pressure is 3 bar (44 psi). Recommended tyre width is 2.3 to 2.6 inches. The 30mm internal width keeps the tyre cross-section correct for XC race performance, rounded, well-supported, and grippy at the pressures that matter. 28H hole count, ERD 592.5mm, max spoke tension 150 kgf, recommended 110 to 130 kgf. A 100kg combined system weight limit (rider plus bike) applies. 

Five-year manufacturer warranty on the rim, 3-year Crash Replacement Warranty on the rim at 50% of the current retail price, The Trust Guarantee (register within 30 days of purchase at conceptspeed.co.za/register) on the rim.

Ultralight does not have to mean fragile. It has to mean fast. This rim is both.
