The fastest way to the top is with the RX25. There is no denying that when climbing, weight is of the utmost importance. Mass is the biggest enemy of performance. That‘s why we‘ve made the RX25 extremely light so that every valuable watt of energy can be used by you. With only 358 g per rim, it is the embodiment of light weight with no limitations. Despite its light weight, there is no sacrifice to ride quality, durability and power. But we have saved the best for last: It is not subject to any weight limit. Which other carbon rim in its class can make that claim?
