RaceDweeb I had a set of the Hagon black spring shocks on my Speedmaster.They were the bottom of the line shock.I really liked them personally.I put over 20,000 miles on them and they were shot.I bought a set of the Progressive this time and they are ok,ride real nice.When the Progressive are shot I will probably get the Hagon Nitros,more money I know but I think they will be worth it.
