Abstract
A twist-grip shifter for bicycles having a twist grip or grip part which is actuated by the rider's hand to change the gears of the bicycle, and a cable winding mechanism or coil wind-up mechanism. The twist grip and the cable winding mechanism of the twist-grip shifter are connected to one another, and debris and other contaminants can be prevented from entering the interior of the twist-grip shifter near this connection by providing a contactless seal or a friction seal. The contactless seal includes a projecting collar on the cable winding mechanism which extends into a groove formed in the twist grip. The collar of the cable winding mechanism essentially does not contact the groove of the twist grip. The friction seal includes a lip or flange formed from the rubber material of the twist grip, which lip then contacts a portion of the collar of the cable winding mechanism.
