Technology:
Suitable for use on predominantly paved and partially unpaved ground with a slight slope and a temporary loss of ground contact as well as drops of up to 15 cm.
Ratchet EXP
A ratchet and a threaded ring are integrated into the hub. This reduces the number of components required, resulting in less wear and tear and a lower weight. In addition, the heavy-duty and reliable ratchet system can be easily and quickly maintained. The no-tool concept plays a decisive role, as it allows the freehub to be replaced without any tools. The freehub has two ratchets which engage simultaneously. This means that the contact surface is large and the point load is kept small, which relieves the material and allows the freehub to work particularly reliably and precisely.
Pro Lock
The nipple thread is coated with two-component adhesive to increase the durability of the wheels. It can still be re-trued several times without any problems, but the adhesive strength decreases slightly. The connection between the spoke and nipple cannot loosen by itself.
