Hub play must always be gauged with the wheel fitted and tightened in the frame or fork. Tightening the quick release skewer significantly increases the lateral pressure
exerted on the bearings. Therefore:
• if there is play in a wheel not fitted into the frame or fork, it may disappear once the wheel has been fitted;
• if there is no play in a wheel not fitted into the frame or fork, it is possible that tightening the quick release skewer will over-stress the bearings, thus damaging
them.
Adjust the adjustment nut by fully tightening it and then untightening it by a 1/4 turn, so as to close the quick release lever (CLOSE position) with a suitably large force.
However, a too large tightening force may damage the bearings.
This tightening force is a subjective parameter that is directly dependent on the end user, and as such it is difficult to accurately determine the optimum bearing adjustment
at the factory.
In order to avoid any problems for your customers, we factory set bearing play by simulating an extreme quick release tightening force.
There is therefore likely to be some play in the hub of a new wheel fitted to a bike with a lower quick release tightening force than that used in the factory.
Apply the following procedures to set the amount of play.
