Range Information
These blocks have the strength and durability to meet the requirements of racing and cruising. Block cheeks are manufactured from the highest quality alloy for maximum strength. The cut-away design minimises weight and allows easy fresh water rinsing of salt and debris from the bearings. Blocks can be disassembled for servicing or customisation.
