Thanks Nigel, Im told a 21 shock will fit into an 18 (its alittle longer so i beleave but i dont know by how much) an SP unit would be great tho. Mines only an MC18R5k and an R model but i like the rear of my bikes to be pretty high and im pretty big so the adjustability of an SP unit woudl be perfect. Any ideas of how much you want for the SP unit? You can email me at StephenRC45@aol.com if you like

cheers Stephen

hope andy can tell me if im right here too....
