hello all

I have a tt1 in that seems to have an overly heavy spring on the rear and excessive preload. it calcs as a 9.5. does anyone have a recommendation for spring rate?

Hi Brad,
If you ask Wilber's about their TT2 shock article number 641.239.01 that spring is too heavy but adjusted almost right off its ok for 83kg, I'll find out some more.

Brad, the spring has 59. 59. - 150 written on it which apparantly means 59mm at each end and 15nm spring rate.
Hope this helps

15 sounds about double what it needs to be. can't think of another reasonable explanation though. thanks for looking.

Ciao Brad, 9.5 should be the kg which develops the spring of your shock, I think it is right for your weight, maybe a go loosening all preload, and see if the plumbing is blocked by dirt, a hydraulic too hard makes you look very stiff even soft spring.

I hope my English is understandable.

At your disposal. Car lo

it is an ohlins shock that is set up oddly with what looks like a showa spring. it has only 13mm sag with the rider on board. we'll go down to a 7.5 and set the preload on it as required.
