I have a pair of genuine Factory Connection used 1.7kg fork pressure springs for sale. They made a huge improvement on the trails against roots and rock gardens. I ride mostly MX and they are just too soft for me @ 215lbs for the track. They were sold me as part of a FC re-valve GNCC set-up. I'll like to get $30 and could ship either $4.95 priority mail or whatever is the cheapest.
