> Click image to enlarge New for 2013, we are bringing you the first Rolf Prima carbon XC mountain bike wheels. Designed to be tough enough for regular training rides but light and responsive for race day, the Ralos9 CXC is built around an 27mm all-carbon clincher rim and our custom XST+ hubset with a titanium CNC'd freehub body.
Like all of our wheels, they are hand-built by us in Eugene, Oregon and have been raced, ridden and hammered through the Oregon rocks, roots and steeps. Need a light carbon race set that you can use with confidence for training - you've found it.
