I have an early 2000s S works m5 hardtail frame built up and I am running Marzocchi Bomber MXC 2002 air forks. They seem pretty pogo stick like with the performance which I can live with but would like to try and adjust them a bit if possible.
More of an issue I think could be the height of them, I did have some Manitou forks on a previous bike also same frame size and style but the axel to crown was 450mm on this it is 480mm so the front end angle is increased and the bike is sitting up higher which does affect the handling? I measure the travel length to be 110mm and am i right in thinking they did an 85 and 105 travel in this model? Any advice to get this set up better or I may have to try and source some more forks, but these are also running v brakes so getting 26 v brake forks that are still in ok shape and light ish is not easy nowadays is it?
I had the 105mm travel so yes, they came in that size. To adjust the damping you need a long hexagonal rod with a slight spike that they came with. You insert it down the air side to adjust a mechanism at the bottom of the leg, mine needed regular tweaking as it would wander sometimes.
I think they were adjustable down to 80mm travel internally so that might be an option.
They came as 100mm but you could buy spacers from ukbikestore to reduce them to 80mm.i still run a pair and like them.you need a long hex tool to adjust them.you may be able to add some heavier oil. I am sure tftuned could adjust them for you.
