The CrampBuster is the simplest cruise control out there. It wraps around the twist grip, allowing riders to maintain throttle with the palm of their hand. This permits the relaxation of otherwise tensed forearm and wrist muscles. Made of a durable polymer, this device is installed in a few seconds with no tools, and comes in standard 1-1/8 inch and oversized 1-5/16 inch versions for cruisers with narrow and wide paddle styles to suit various needs. The price of this product is $11.
