MTB suspension forks, the version making me shudder being from the good days when they were sprung and damped with chunks of rubber and bolt that held the stanchions to the sliders was accessed via a really long allen key inserted from the fork crown end. For best effect you'd ride the bike through a river every day for six months and jet wash the thing at every opportunity before complaining to the shop that the forks were seized. Obviously at this stage the bolt that needed removing was also seized and, being soooo long, the allen key supplied by Manitou at the time just wound up like a torsion spring. Happy days.
Time flies, just occured to me that the last thing i had to do with the cycle trade was over seven years ago. Fittingly it involved Madison putting me up in a hotel for a couple of days while i helped them out with a Manitou recall God knows how many Giants (took three of us working flat out 2 and a bit days) had been shipped into the UK with a dodgy rebound valve, all had to be unboxed enough to swap out the damper assembly without destroying the packaging or spilling oil everywhereWould you believe that's 11yrs ago now
