just to update ...ive got the springs in and ive been offroad today

...after some messing ive backed the hagon off solo ..to no added preload and around 1.25 rebound ..this seems to suit the steady pace i ride ...

the springs were fitted with 660 ml of 10w oil ..these have scored a great hit with me ..its just all round better on and off road ...even purposly braking hard on big bumps was more than ok ....overall im delighted with the result
the preload wound level with the top of the fork leg seems good on and off road ..i dont think ill be messing with it further unless its heavily loaded
the road quality is much improved .. i would recomend them without reservation
