The unique combination of the aluminium body and moulded rubber flap ensures that the rim lock has a firm and strong grip on the tyre. The serrated edge of the aluminium body secures the tyre against the rim, while the rubber flap reduces abrasions and, in turn, reduces the heat of the tube.

Features:

• Aluminium body increases grip of the tyre
• Rubber flap protects against abrasions and reduces tube heat
• Serrated edge on body secures tyre against the rim
• Rim lock size related to rim width
