pulling the tension adjusting nut, by way of the skewer, against the other dropout. The amount of clamping
force is controlled by the tension adjust-ing nut. Turning the tension adjusting nut clockwise while keeping

difference between safe clamping force and unsafe clamping force.

turning the lever like a wing nut with the other hand until everything is as tight as you can get it will not
clamp a cam action wheel safely in the dropouts. See also the frst WARNING in this Section.

The cam-and-cup system on your front wheel will have been correctly adjusted for your bicycle by your
dealer. Ask your dealer to check the adjustment every six months. Do not use a cam-and-cup front wheel
on any bicycle other than the one for which your dealer adjusted it.

assembly can result in brake or gear failure, which can cause you to lose control and fall.
