Title: Progressive springs upgrade
Post by: DTTW on Monday, 12 June 2017, 10:35 PM
Is there someone who could explain the difference over these two: Promoto Fork Spring progressive AND Wilbers Fork Spring - Zero friction - progressive?

Should I put my money on the zero friction model or is the "regular" one a great improvement over the originals? Also, should I consider Hagon springs instead?

mate, had a look at box my springs came in, just says wilbers brilliant suspension. no numbers or model.  i know nothing about any others. for a few bucks get the wilbers. i also got their oil. no idea if better or worse than others, all i know is that front end is brilliant, as the box says. read all the stuff about linear versus progressive, confused me. just went with these. got suspension shop to re work, set up for me. best money spent on this bike. can remember coming home from a trip wed done before, last bit a bit bumpy. was thinking just how much better now. shop set all the adjustments, perfect. too hard for me , all those knobs and screws. now i ride it and those adjusters dont exist for me.

sorry for short reply Vlad. yeah, theyll fix both ends. not knowing your rear shocks but can re build whatever. i was over all the adjustments, tried multiple times, now i might ramp up rear springload if two up, thats my adjusters sorted. adjusters on front, should put superglue in them, never change or think about anymore. just works fine.
