The Simson Kickstand Solid small is an adjustable aluminum kickstand with a normal wide mounting plate (30mm). Can be customized for each wheel size by cutting it down to size by the size index engraved on the back. Ideal for city bikes and hybrid bikes up to 28 inches. The rubber base provides extra stability. Saw the kickstand to the desired size with a hacksaw and mount the kickstand on the bike using an Allen key and the supplied Allen bolt.
