maintainence for suspension seatpost(3 posts)

maintainence for suspension seatpostturtle
Oct 21, 2001 9:06 PM
I have an early generation (at least 5 yrs old) USE-sx seatpost and I'm curious if I need to do any maintainence to it. I have no idea how the post works or what the internals are. I do know that it uses elastimers but what else? I weigh about 185-190 so what color or how many elastimers do I need to use.

Thanks in advance for your help,

Well - I have no real experience with that seatpost, however - I imagine you care for it in the same manner you would care for an elastomer based suspension fork - if the ride is as you like it, don't worry about swapping out elastomers unless the ones currently in there are falling apart.

Open up the post, clean everything as best you can (no need for a degreaser - just use a couple of clean rags - make sure you get all the dirt, etc. out) - then re-lube everything with an elastomer-safe lube (something like Judy butter) - this includes the elastomers as well as any seals, shafts, etc. - then reassemble everything, adjust the preload to your liking and you should be good to go! If you do need to replace elastomers, the stiffness is indicated by the color - blue is up to 85 lbs, green is 85-120lb, yellow is 120-174lb, and purple is 174-225lb (as with forks, I imagine this is more of a guideline - if you want a firmer ride, get a stiffer mcu, if you want a softer one, get a softer mcu - I don't know if the post uses one big or a number of small mcu's, so you may or may not be able to mix and match. (the newer posts are also a spring + elastomer stack, if yours is similar, you can swap the spring out in the same way (same color code applies))

Check out the Use website ( for more specific info

For more the "tips and tricks" sort of thing, I would recommend posting on the MTBR board - there are some pretty knowledgable suspension guys over there whom I am sure could help!
