CrankBrothers Joplin 4R Seatpost Review - BikeRadar

Now thats what I want in my stocking dont think the misses will stretch to it

still no 27.2mm version :(

£240 for a seat post? Has the world gone mad? Good idea, but way to expensive.

+1, stupid price!

(I still bought one though...)

£240 is pricey, but it's not just a seatpost, salsarider69, It's half a set of forks!

And who gives a crap if it doesn't come in spindley 27.2mm? get yourself a proper frame rather than one made lemonade straws!

I believe this seatpost to be with us in the new year, so those asking santa for one, are going to be sorely disappointed.

It's expensive, but I'm going to be asking the Easter Bunny for one of these bastids, and he'd better come up with the goods, or I'll smash all his eggs, fat little bugger!

Had a Joplin on my Nomad, and at 14st the saddle cracked in the middle when it flexed under weight and hit the sharp thread under it - absolute design flaw. Further, while in Malaga doing the trails and mountains, a rider in my group with a Heckler and Joplin, had a horrific fall as the saddle literally just came off. In the middle of nowhere he had to ride back concussed and bleeding and we all took turns to ride the bike as you had to stand up the whole way. Suffice it to say, I changed to fixed thomson set back and charge saddle and have been very happy since.

crappy as many products from crank brothers......i mean plastic and bearings....

Great for fashion victims with plenty of $$$$

long term use and side to side play is major concern. My Joplin3 has tons of side to side play.

also, can you now pick up the bike with the saddle and not mess up the mechinism like you do with J3? (ie introducing air into system that now needs bled)

frenchfever, COMPOSITE and bearings, they use plastic for the barbie dolls you buy.

Fashion victim? Not at all, For people who don't want to stop mid trail and get in the way of everyone else, probably like like you.

With plenty of $$$? I bet you'd spend £150 on a blue rear mech, and £££'s on little alloy bolts in red, tw@

Bonjour monsieur

is this compatible with Fizik gobi xm?

I've used the new joplin 4 for about 4 months and it's going back to the shop. After 3 months, it came short, about 3/4 of an inch to full extention - and no Viagra to help it out. A few more weeks of ridding and it wouldn't come up without pulling on it manually. I've had it. I have a Gravity dropper turbo on order. I don't want the joplin back, but we'll see what Crank Brothers will do.

I have a 3" remote version on my XC FS bike that's still working acceptably. After 6 months on it, it doesn't extend all the way anymore; maybe 10mm worth of extension I can get, but only if I pull up on the seat, lever style. I had a couple of times where I got airborne and landing on the saddle with a violent thud and it survived, but I think that may have caused some issues.

I got the 4" version and it works great, except for the usual cons, such it rising when you try to lift the bike by the saddle and not having any included cable guide solution for the loop the cable makes when fully dropped. Not sure if it counts as a con, but it only comes in setback.

Only thing I have to compare it to is a Reverb, which doesn't lift when you pick it up by the saddle (unless you pull really hard while holding the bike down). It's zero setback only and 5" only. It comes with a neat guide that I mounted under my seat collar to keep the cable out of the way of the rear tire and my legs--the excess cable actually ends up in front of the head tube when I fully drop my post.

You UK guys are getting gouged... paying the same MSRP amount, but in UK currency, which is at least 60% more than USD. Reverb cost me $245 though, while the 3" cost me $125 and the 4" cost me just under $200.

I love it when it works and I am fastidious about maintaining my bike but the Joplin is an absolute shocking piece of rubbish! OK, you have to service them (I'm not fussed about this) but the day after your last service, when you are in the middle of hell weather in Wales and it just 'stops' at the start of the days ride. You are left with a broken, expensive, heavy seat post that cannot even be lowered as low a standard post as it has a collet and shaft by design. DO NOT BUY THIS POST; DO NOT BUY ONE CHEAP OF 'BAY IT SUCKS!

SUCKS - Worst MTB purchase ever, do not buy, mine is not a manufacturing fault, been back on warranty twice, still complete bobbins.

Buy some Gore-Tex cables and some beers and smile because they work...

Great when it works, but it doesn´t for long. The remote lever is excellent, it hat a smooth action and worked well for 4 months. Little side play not really bothersome. Then it slowly started to lose travel to about 1/2 of the original. Send it in to crank brothers via the dealer - it took them 6 months to reply (because there are so many going back). The answer was that it was my fault because I crushed it by over-tightening the clamp. But I could get a new one as a replacement for 100 Pounds. Not going to do that.
