Ideal for climbers, although not just for them: the Fulcrum Racing Light XLR wheelset. Enhanced by carbon fibre hub bodies that act on Cronitect steel bearings with CULT ceramic ball bearing technology, improving smoothness nine fold in comparison to standard steel versions. The low profile rim is laced with a 2:1 spoke ratio on the rear, doubling the spokes on the freehub side to obtain a snappy response during sprints & on the climbs.
