Yes, it's ok and to be expected. Even expensive dropper posts, which work via the same basic principles as telescoping suspension seatposts, have a bit of side to side movement. For the suspension seatposts, just ensure that the collar at the top of the stationary (outer) portion of the seatpost is firmly hand tight.

An up-down movement is perfectly fine – that's what suspension seat posts are designed for! For the side movement it's a bit more complicated. A suspension seat post is basically two tubes sliding into each other with some suspension mechanism. This requires two things: the tubes need a little clearance to move within each other and they need a mechanism ...

I have used a couple of these seats over the years - the ones I had did have some movement - noticeable when riding. Although not ideal, you do get used to it. It comes down to cost - it would be more expensive to precision manufacture them with no movement, but at some point people would stop buying, and another point, might as well buy a full suspension ...

Thank you for your tip, Emyr. I ended up using my screwdriver and hammer method to work around all of the brittle elastomer sections. However, at the bottom of the last section of elastomer was a round piece of plastic with a hole in it. I did just what you suggested to remove it -- I bent the end of an old spoke into a "J" shape, and pulled it out of the ...

Headshok is super-stiff, light and solid. There is virtually zero stiction and the damping is butter-smooth. I have a vintage, 2001 Bad Boy Ultra with Headshok and only recently re-built it (2013) – that's 13 years of reliable operation! The guy who serviced it said I'll easily get another 15-18 years' use, as the updated bearings and seals are even better ...

I've never dismantled a fork intending to reassemble it, but... Could you use a J-end spoke or a knitting hook to pull the elastomer rather than pushing it? You should be able to get plastic knitting hooks so the inner surfaces aren't scratched.

If you want to do it the "professional" way, you would need some quite specialist equipment to fill the brain unit with oil and nitrogen properly. However I have heard of people doing it on their own. The most complex tutorial I've seen is here: http://huckingkitty.com/forums/viewtopic.php?f=11&t=720 (note: I havent tried this and can't guarantee that ...

XCM is an entry level fork - typically found of bikes at the low end of the price range. Its not hard to imagine you have out grown the fork and it is limiting your enjoyment and performance while riding. The only way to tell if a better fork is needed, (or is that wanted?) is to take a bike with a better fork for a ride. The main consideration is how much ...
