Have bought shocks from a local shop for £170 they are the eco line model middle of the yss range ,Had Hagons on be fore but 2 up over The Strines hair pins near Sheffield i popped the seals in them .Found out from hagon they are not serviceable told to just keep the springs and bin the rest .Have had some ebay specials on for the last year been alright but bike feels like its a hinge and bounces and wallers round corners .So decided to treat the old bus as its 30 yrs old next year to a suspension overall .Fitting new tapered roller head bearings putting the progressive fork springs back in put the right amount of oil in this time and new rear shocks .....Dead line 1st MARCH 2016
