I have just rebuilt my forks,
Well 2 sets as I swapped links and rods over.
On both sets the copious amounts of grease applied many years ago had been contaminated with so much road crap the springs had nowhere to compress.
Not really sure what the grease is for.
With a rod through the middle they can't flex and touch the inside of the leg and we don't grease the rear spring.
So is it to allow the spring to slide on the rod?
If so wouldn't modern graphite or silicon sprays do a better job.
Have I missed some thing.
Also would a suitable plastic sleeve over the bottom half of the spring Keep things cleaner.
