Supplied as a 270mm assembly, which can be easily trimmed down to suit the cistern. A taller/longer version is the Grohe 43486 000. If your toilet is not flushing properly, check that the bellows and button are working properly before purchasing. Genuine brand new Grohe product, covered by a Grohe manufacturer's guarantee.

The Grohe single flush valve design eliminates the need to remove the entire cistern to service the valve in the future; simply pull the valve upwards and the entire top mechanism lifts right out. All that remains is to clip the new valve into place, adjust the valve to the desired height and connect any other mechanisms that may be required.
