Bikehard Handlebar Bottle Cage Adapter MountThe BikeHard handlebar adaptor mount is an ingenious little alloy clamp that provides the same mounting bolt spacing as would be found on the inner triangle of a bicycle frame. With a single bolt, this bracket can be attached onto any handlebar, at any angle, and is primarily designed to accept water bottle cages. However, an infinite amount of accessories can be mounted, since the bolt spacing is an industry standard 64mm. Relieved internally to accept rubber grippers, this little clamp can hold firmly in place even with a full water bottle. Comes with all necessary hardware. Purchase for one Adaptor Mount.817616022261
