    JOPLIN-R SEATPOST for my MOJO - R 31.6mm?

    Hi,
    I decided to add a JOPLIN-R (remotr) SEATPOST to my Mojo.
    1. Do I need a 31.6 or a 30.9 mm?
    2. Before buying: anyone tried this thing??

    BR,
    Doron.

    The Joplin is nice. I run the GravityDropper Turbo, which does the same thing, but is lighter and I like the functionality a little better. But the GD is uglier and doesn't look nearly as nice on the Mojo.

    Either way, you'll love it and if you ride all mountain terrain it will improve your riding like no other upgrade IMO.

    I can't remember the size, but check the geometry page on ibiscycles.com. I had to use a shim, but no problems.

    30.9. I run one and love it. Also, try and get the Token brake line guides for a Fork and use it to run the cable for the Joplin as it stops it rubbing your frame.

    30.9? But the ibiscycles website says:

    Look at:
    http://www.ibiscycles.com/downloads/...p_Guide_08.pdf

    page 3 says (quote): "The seatpost diameter is 31.6 mm."

    so??

    Ditto to the 31.6 post size i had the maverick version and they are a great idea but be warned if your a clyd like person im around 230lb they don't seem to last that long so far ive had jams (ie not lowering) or it just would go down all of it's own so to fair i have given up with them after my third one and just put my thomson back. Anyhoo good luck Bat.

    well this is weird, but I definitely have a 30.9mm Joplin. I also used my Thompson Masterpiece from my Nomad which is 30.9mm too. So either Ibis changed their frame just for my bike or they've now switched to 30.9.........

    Ibis, what's the story?

    Well, naturally you can install smaller diameter seat post into the frame but everybody I know are using 31.6mm posts.

    Well my 31.6 is pretty darn tight so .7 of a mm is probably ok!

    31.6 for sure. I have a Joplin R and love it! Initially I thought I would take it off for races, but I used it in a XC race on Saturday and KILLED the other guys on the rocky, technical descents. Was a joke how much faster I wasgoing on the downs.

    For general riding and AM action is simply brilliant. Just keep it clean.

    Agree, and ignore my post. I am running a 30.9mm with no issues and I swear blind that I saw the right post was a 30.9mm on the Ibis site, but I am quite obviously wrong. Still, seems to be running no problems.

    Hans - anything I should watch out for as I do have tighten the seat clamp a little bit more than normal but otherwise it feels fine........

    I'm running the 31.6mm post. I just used it for the first time yesterday and to be honest I can't see ever going back. I was able to do some trail features that I'd never have done in the past because my center of gravity was all off (either too high or too far back.) Absolutely wonderful!

    Does anyone make a shim to go from 30.9 to 31.6?
    I'd hate to buy the 31.6 version of a seat post, then later find out I can't use it on a future bike?
    Not many frame makers use 31.6, but a lot are using 30.9 these days.

    I wonder if just making your own from a coke can could work since it's such a small difference.

    Joplin = Speedball for those who might ask .

    Post some pics of you Joplin when you get it. I wonder if CrankBros is going to release a lighter and improved Joplin any time soon?

    Get a Joplin

    It's definately worth it. I've cut up a slap-sock to keep it clean and operating.

    I'm running a bmx diameter seat post and got this shim from Universal. I can't comment on it's use with the joplin/speedball however.

    I ordered a Kind Shock I900R seat post. I received the post today, but I got post in 30,9mm diameter of 31,6mm that I ordered. If I return it will take few weeks.. I cannot return it if I try it. Should I return and wait or will there be a problem using the smaller one?

    I would return it and wait.
    I don't think anyone makes an adapter to fit a 30.9 post into a 31.6 tube. There are lots of adapters for the 25.4 size, but nothing for the 30.9.

    If you try it, it will likely be loose and slip down all the time. Then you'll either have to make your own adapter, or buy another seatpost that's the right size.

    I've found a few interesting things about my Joplin (which I love!!) Ridign in some of the wet/muddy conditions lately;

    Keep the seatpost lubed
    keep the cable clean and lubed
    don't tigthen down the dust seal too hard (red ring)

    I noticed when the cable (just like a derailleur) gets dirty or the shaft gets dirty that the post doesn't operate smoothly or easily. No big deal though, before each ride I put some Tri-Flo on the shaft and pump the seat a few times and drop a bit of lube down the hole where the cable comes out and its good to go!

    31.6 is the right size for Ibis, but I guess you can use an adaptor

    I have a Maverick Speedball that was originally in 30.9. I was able to order just the tube in size 31.6 from Dirt Labs and swapped the rest of the existing post into the new tube. Tube was $45 + shipping. According to the site the tube will also work for the Joplin. Site only list the 30.9 tube, but send an email and they should have 31.6 size in stock. http://www.dirtlabsstore.com/product...=2&productId=1

    Does it make that much Difference? I ride some rather technical trails and have taught myself not to lower the saddle.?
    And is there any play in the saddle? "side to side movment?" as that will drive me mad....

    if you'r toptube length is short it can make it easy to drop behiind the seat and the dropper won't be as necessary. But if you are at all stretched out on your bike a dropper is SO nice. On my old frame I ddn't really need the dropper although it was nice to have. On my newer bike with a more stretched out frame its almost mandatory as its much harder to get my body behind my seat without hitting the back of it.

    Yes the Joplin has play side to side but you never notice it while riding...seriously

    I was very skeptical before I finally jumped on the bandwagon, but I am a complete convert to the concept. It has made a huge difference in my riding through technical downhills. I at first thought I'd use it a couple times each ride, but after a few rides I starting dropping my seat more and more because it is so effortless (make sure you get one with bar-mounted remote). You will get used to the slight play in seat almost immediately.

    After a year it is now a natural part of my riding, like using my gears---dropping with nearly every downhill section, even short ones. The added feeling of comfort and control it brings has made me faster and most importantly has made riding more fun.

    I know at least 15 guys who have bought one (various brands), and not one has been even slightly disappointed.

    This post will not develop any side to side slop and has been rated highly in the uk mtb magazines. I believe they have released a version with a nicer looking seat rail clamp recently. Also has infinite travel adjust, not predetermined drop steps. Its cheaper and is the one ill be buying

    The Joplin should be more problem free than the Speedball. I use the non-remote version for weight savings and less cable clutter. I have no problem raising and lowering the saddle on-the-fly in real moutainbike situations. I could have had the remote version for $25 less!

    I think that maybe, you need a longer stem on that Mojo... The saddle is a little too far back in those clamps, imo.

    Related Joplin Questions

    I have been thinking of adjustable seatposts for some time. The Joplin appeals because.....it is infinitely adjustable, not too heavy and can be bought at my LBS and warrantied in Canada.

    However, given the "all mountain" use of our Ibis bikes and some pretty steep downhill sections I have two questions?...a...is three inches enough seat post travel???...and b....in reading the thread above and the mtbr reviews, it sounds like it is prone to failure and problems???.

    Any helpful comments appreciated.

    If you are a big tall guy, maybe three inches of drop won't be enough for you, but it depends on how much seat post you have exposed in your frame.
    I've been testing the Speedball and the Joplin for quite a long time now, and have had no problems at all with either one. The only gripe I had was with the saddle rail clamps, which I considered to be slightly under built, but they have not failed and once I tightened them down hard, they have not moved, either.
    Regular maintenance involves cleaning the crud off the sliding post, and squirting a shot of teflon lube on there to keep things sliding easily. The addition of the remote Joplin transforms the steep downhills and techy sections into a much safer and faster proposition, and once you fit it, you will wonder how you ever did without one.
    Being able to easily get your butt right over that rear wheel "on the fly" when negotiating steeps is great, and helps to prevent those terrible endo's we all sometimes suffer from.

    Another bonus is being able to position the saddle exactly at the height you want it for different pedalling situations...instantly, without removing your hands from the grips.

    In my opinion, anyone who regularly rides AM should have a dropper post fitted...it just makes things so much easier overall.

    I've got the Maverick Speedball and have no problems. Lube the screw for the rails and there's zero problems with that. Keep it clean. I had one problem with it falling down during a ride. I took it all apart, tested the air pressure, filled it up a bit, didn't fix it. Turned out I just needed to run it through 4 or 5 cycles and it corrected itself. I will not go back to a fixed post - it is incredible.

    I actually rode with a guy who had the Joplin this week who was complaining about his seat angle moving when he bumped it hard, and he had no idea about the concept of greasing the screw - he didn't even know why that would help. These are the kinds of people I worry about writing reviews. He actually complained about the side-to-side movement on it as well. I definitely feel it when I move the bike around by hand, but when riding it is a complete non-issue.

    I don't like the idea of shims for the GD and the AMP, and the Specialized post sounds like it's heavier and could have issues as well (though it's tough to gauge if it's user-related yet). That KS post looks darn good with tons of travel, but it sounds like it's much heavier (not sure, seems there's various weights given). So that leaves the Joplin. Do it.

    DH_WP: Joplin perfect for Tokai, Eden, sections of Jonkers and Delvera. It's a blast in Lebanon. It does have some side-to-side play so rather go with a KS.

    I have found that 3" is not not enough for me. Partly cause my BB to saddle height is 75cm. I like my saddle to be fairly high (not too high, just 100% where it should be for pedalling). If I drop it to 72/73cm it helps with the 3" drop, but then it's not where I want it for climbing and general riding.

    My seatpost "cape" has kept the Joplin smooth and operating right through winter. If you don't look after it, it will give you issues. But all in all it's freaking brilliant. Done some rides this week with a "normal" seatpost and hated it. KS here I come!

    i can't believe no one has mentioned this one yet.

    http://fezzari.com/products/index/Fe...Seatpost/85/42

    no side to side movement, infinite adjust, 5 inches of drop, will not extend when lifting by the saddle like the Joplin does, better looking remote and less expensive.

    i have had a Joplin and this hands down is the best, note it does take a little breakin but once it is it is magic

    only comes in one size......MOJO size 31.6

    i have had a Joplin and this hands down is the best, note it does take a little breakin but once it is it is magic

    only comes in one size......MOJO size 31.6
    Purely being ignorant but there is something about ths post that just "looks" cheap. Looks like a walmart knock off of the Joplin. I'd have to hear more reviews

    i do admit the clamp could be a little more sexier but it's mostly hidden by your seat and it actually clamps way better than the Joplin.
    i rode a Joplin for close to a year, it was good but i did not like the side to side movement although you do get use to it, but every time you grab your bike by the seat it reminds you its there, second is that when the Joplin is down you can actually raise the seat by grabbing the seat and lifting, now when bombing down the trail and you are use to squeezing the seat with your knees that is very annoying when the seat moves up on you.
    third thing is that Joplin is only 3"drop not quite enough in some situations.
    i have been riding the fazzari(it is the ks i900r renamed) for about 6 months and have not had one issue yet and as far as people think its "cheap" i weigh 240 geared up, and ride everything i can get my wheels on. cheap won't last with those parameters ,i know

    Rainman, you're right. The picture shows the initial setup just after my new bike buildup ( well, only new frame, fork and seatpost) without any saddle position adjustment.

    Anyway, in my final fine setup the saddle is still a little bit back. The reason is that I had to decide between an S and M frame sizes (I'm 1,67cm tall). S size is a bit small for me but when I tried the M size, I felt it slightly big... and also found the standover heigh too "risky" if I have to jump out of the saddle.

    The solution was: S frame with the saddle a bit back to adjust properly my position against the pedals.

    The saddle mounted in the Joplin R seatpost now looks like this:
