The Arkel Cam-Lock® hook system
Take your pannier on and off in seconds, no rivets, serviceable with standard bike tool.
Pull up the handle, it opens the cams. Release the handle and the cams firmly lock on the rack tubing. No need for special inserts. The Cam-Lock® will automatically fit rack tubing of 8mm to 15mm diameter. Covers the vast majority of racks on the market.
The hooks and rail are made of super strong aluminum (No plastic hooks that will crack or break). The hooks are lined with a nylon insert to protect rack finish. Thermoplastic insert inside cams firmly grips to the rack tubing and prevents any creep or rattling.
