Does a suspension seat post actually work? im thinking about giving one a try.
so is it a pure comfort thing taking the lumps and bumps out of the road and trail or is it abit more technical than that?
i get the impression that when the going gets rough the post is going to bounce you right out the saddle every two seconds.
any help to shed some light on this then that would be great
thanx
Used to use a Rockshox one & it worked fine, took the edge off sharp hits & saved my lower back from getting a beating until I strengthened it up a bit.
Don't use one now though, a decent SDG saddle takes care of most impacts fine or maybe I'm just taking it more easily..
When things get rough it didn't make any difference to a solid post for bouncing me out, just took the edge off the kicks.... thinking back, it probably allowed me to keep things under control a bit more during really rattly stuff but I just hang my *rse over the back instead now.
It's not a cheap full sus option though, hope that helps a bit.
I'm currently trialling a Cane Creek Thudbuster, which has surprised me by working a lot better than I expected. Not a good as a decent well-adjusted FS bike, but a fairly decent simple alternative imo.
I had a Thudbuster on my Xizang for ages - I really liked it and missed it when I sold the bike. You're right about what happens if you get caught sitting through a really big bump - the post will catapult you (smoothly) into standing, not so bad. In general you can sit through a potholed stretch of road though.
We still have one on the rear of our tandem (the stoker can't see the bumps coming).
The elastomers can split when they get really old (over 5 years in my case) - carry a spare.
Maybe you can find an old one on ebay to give it a try, rebuilding it if you like it.
Slight hijack, but we've got a spare USE shockpost sitting in the garage. It was on the back of the tandem to replace our original Coda seatpost but became surplus when we got the full-suss. Only been used a few times.
Drop me a line if you're interested.
Cheers,
Rob
I got my first one as I used to have a real tricky bumpy climb.
It let me stay seated to keep weight on the wheel without getting kicked out of the seat. Running a Bracer that needs a service so experimenting with a ti post once it turns up.
rather informative thankyou, i may just give one a go, any brand reconmendations?
I'm on my second "use sx" seatpost. had to get second one when I came back to hardtails. as previously posted not a replacement for FS, but good for tech climbs and all day epics. USE have different springs for your weight, and are fully servicable. wouldn't be without one 
I have two USE posts, both over 5 years old and going well. Occasional clean n grease keeps them going. Spares availalable from CRC etc.
Got a USE one in the Kielder100 giveaway last year and was initially a bit disappointed that it wasn't a normal seatpost 'cos I was wanting to replace a crappy old suspension post that came on a cheap hybrid. Turns out it is pretty good. Just like a normal post but more comfy, and certainly more controlled than the cheapo one.
