I'm wanting some Hagon progressive fork springs for my SF but all they have listed is a CB1. Am i right in thinking that these are the same forks as my SF? Also what weight and amount of oil should i put in with these springs, i'm about 11 stones in weight if that makes a difference but would like a slightly firmer ride with less dive when braking hard.

Get in touch with DPS racing they will be able to help you. They are in keighley. Dont put progressive springs in tho, they are rubbish. Im running some springs from dps with home made spacers and 12.5 wt oil, best upgrade i ever made!
