6.3.2 Wheels: Using the RWS system
In order to tighten the RWS system (ratchet wheel mounting system) turn the lever
clockwise whilst holding the adjusting nut (on the other drop-out). The functional
principle is also represented in the figure below. The minimum hand force required
is 15 Nm. Depending on the frame or fork construction it may be necessary to turn
the lever several times. To open the system turn the lever anticlockwise while hol-
ding the adjusting nut (located on the opposite side of the hub). The clamping de-
vice must always be able to be opened and closed without tools using the lever.

Checks to be carried out before each ride
Always check your RWS system before each ride to make sure that the wheels are
correctly installed on the fork or the rear drop-outs. This is especially important
after leaving your bike in a public place. Make sure that the tightening force of
the RWS lever is at least 15 Nm.
