    Suspension seatpost springs

    Hello, i have a question on an option that seems to be worth considering if you own a Rockshox suspension seatpost or anyother all elastomer seatpost shock.

    i had just unscrewed the bottom piece to dismantle it, and what came out was a plastic I spacer (which i plan to replace with a stronger metal one) and a 3/4" x 4 3/4" pink elastomer.
    i had removed this to see why the suspension of the post felt so stiff and because of a review i had read on MTBR.

    ok, now what i want to do, is add a spring because i dont like the cheap feel of the elastomer. Can i use a custom spring bought from a hardware store? or is there a specific spring i should use, like a replacement kit from another company? if so where can i find this?
    it should be 3/4" in diametre.
    thanks for any replies.

    I am not sure if RS has retrofit springs but in all likelyhood they will. I have seen other spring kits around shops that are relatively cheap but decent. I will go out on a limb to say that most posts I have yet worked on are virtually identical inside so far as the springs are concerned, so theres a chance RS would apply. The easiest solution is to take the post with you and see if it fits. Shops will usually let you trial fit if it doesnt scratch or anything.

    Thank you for your reply. I see you have worked on parts of this department, id like you to tell me what you think of this post i found in MTBR. The hugest complaint ive seen (and noticed myself) about the RS post is that it does not use a coil spring, but just an elastomer (and a very firm pink one in my case being 150 lbs). And i dont know of an LBS around nyc that stocks susp seatpost springs so readily.
    so here:
    ~~~~~~~~~~~~
    Submitted by James a Cross Country Rider from UK
    Date Reviewed: 7/27/2003
    Strengths: Good and solid feeling, strong and very adjusable clemp, smooth suspension and it works .Weaknesses: Elastomer softens in hot weather
    Similar Products Tried: USE XCR
    Bottom Line: Strong and well adjustable post, both for suspension and saddle position and tilt. Smooth action with no stiction even though I ride with the saddle set well back. During a spell of hot weather (30c) here I noticed that the elastomer had become softer, hence more sag and therefore saddle height wrong. However have experimented with substituting half of the elastomer with a USE medium coil spring and with this set up performance is excellent, very active ., great dael of adjustment on the threaded base cap, can ride over some very rough terrain and absorb all sizes of bumps. Perhaps RS should consider this sort of elastomer / coil spring set up as USE use....
    ~~~~~~~~~~~~~~~~~
    Its just too bad that "USE" company is the hardest thing to google. and anything i find is in the UK. is USE a european company? what can you reccommend?
    thank you for any reply

    I will have to ask around my LBS ring, but I think Mountainspeed made the refit kit. If it wasnt them then it was someone comparable.
