Santa Cruz Bicycles Reserve Carbon Rim 29in

Enticing you to build your very own set of drool-worthy wheels for your 29er, the Santa Cruz Reserve Carbon Rim 29in provides unbelievable strength and unflappable stiffness, now available as rim-only, so you can customize each hoop with 28 of your preferred spokes and favorite hub. Three different internal widths of 25, 27, and 30 millimeters cater to a wide breadth of riding and racing disciplines, from swift-moving XC pursuits to everyday trail rides and rowdy all-mountain thrashings alike. By now, we're guessing you've seen Danny MacAskill trying his best to demolish the Reserve Carbon Wheels, including a number of absolutely savage drops to flat, as well as riding down steep stairs without a tire on, just to showcase the stunning resiliency these carbon rims exhibit. Santa Cruz is calling these Reserve 29in Rims the strongest on the market, seeing they've gone so far as to redesign the impact testing protocol used, just to make sure each Reserve Carbon Rim is up to their impeccable strength standards. Instead of replicating the pothole-like impact test used on traditional carbon wheels, Santa Cruz developed their very own testing procedure that simulates one-sided impacts that normally occur when a rider lands on a square, protruding rock after getting airborne. As they began testing leading manufacturer's carbon wheels, it became readily apparent that most carbon wheels not only broke along the expected bead, but they also failed along the spoke nipple interface, due to the drastic increase in spoke tension as the wheel flexed upon impact. To mitigate these breakage issues, Santa Cruz beefed up the rim bead, increasing the thickness by one millimeter along each side for improved resiliency when you're thrashing the living hell out of these wheels. The engineers at Santa Cruz then fortified the spoke holes with square-shaped reinforcements you can visibly see, which protect the spoke nipples from suddenly pulling through due to harsh impact.
