Just a thought regarding popping in progressive fork springs. When I first bought my hagon progressive springs, initially I just opened up the fork caps and did a one for one swap with the stock springs.
Well the other day I decided to replace the fork oil which had been in since new. The dealer suggested the air gap for the Hagons should be 140mm and the oil I should use is about 10wt.
So before I replaced the oil with the above specifications, I measured the fork sag of my bike just standing upright by itself, and once replaced I measured the sag again.
Well it turned out that by replacing the oil, my forks were raised up approx' 1 inch or 25mm.
I haven't had the opportunity for a long ride yet but tomorrow I go on a 3 day road trip so I'll determine the results then but I can say that on the small rides I have had, the ride is considerably better than before and considering I have 25mm more travel, why wouldn't it.
Of course, it makes sense the 25mm or 1" more travel is due to change in the air gap specifications ie: stock springs 166mm compared to 140mm for the progressives, though I thought the difference may have been due to the different type of spring.
Anyway, if you are like me and just popped in new progressive springs, you
MAY I stress,
MAY find that you lose 25mm or 1" of travel at the same time.
Mind you, I've been riding with the old fork oil specs for thousands of K's and my Sheila handled as well as I thought she should. Maybe I'll find out her handling now is even better.
