2009 Model No Longer Available
Crank Brothers Joplin R Drop Seatpost - 2009 BCS
Hang your drawers off the back of the saddle when ditching elevation, but stop and jack the post up for a climb? Quit it. Penetrate your seat tube with Crank Brothers Remote operated Joplin and never stop to adjust saddle height again. The remote lever mounts on your handlebars where you can give it a quick pull or push to adjust your seat instead of getting off to stop. Drop seatposts have become a staple of all-mountain rides and super-D races all over the planet, and this one gives you the Crank Brother quality you count on.

Must for all All-Mountain and Super D riders

This is worth 500g in gold if you constantly find yourself switching saddle height during your ride.Just make sure when you install the seatpost it is at its highest level before you cut the cable. (I wouldnt know from experience)

This probably isn't the best adjustable post out there, but at this price, it's probably the most affordable. It's super easy to install and once you take it out on a ride, you become enlightened.
You can do so much with the seat out of the way with your legs free to pump, absorb shock, get low over the saddle, twist and lean into corners, get more height on bunny hops, etc. Being able to tuck like a mofo is something a great number of riders have no idea could help them on their ride. It's like going into a tuck makes you go faster through everything--it's actually touted by some as the attack position. You really can't do it with the saddle up, since to be able to use your legs to unweight and pump and to get low, the saddle needs to be low else you'll be like a clown getting behind the saddle when the trail isn't even steep. I'm not shy about hitting jumps on the side of the trail either anymore--before I got it, with the saddle up, when I went for one, it was scary with the front of the biking pitching down, but with the saddle out of the way, I can sail through the air more comfortably due to the position I can get into when I take off.
There's no compromise on pedaling efficiency either by raising the saddle back to the optimum height. I used to run my seatpost about an inch lower than optimal, but now I get the best of both worlds and then some, as i still find myself going back to that 1" lower position, all for a 300g weight penalty. I'm no weight weenie, but I'm sure that extra 300g over your typical seat post is worth the performance you get out of this.
3" of adjustability is plenty for me. With the saddle 3" lower, it's never interfered in anyway and I don't desire for any extra lowering ability. It's at the perfect height for my bike stand to grab the a safe amount of post, between the collar and seatpost clamp. Thanks to the infinite adjustability, I also discovered that I prefer my saddle a little lower for general trail riding, maybe 20mm lower than "max height with slight bend in my knee at full pedal stroke extension".
Downsides: it rises if you try to lift the bike by the saddle while it's in the down position.
1. Is the listed length when the seat post is collapsed or extended?
2. Is there excess than can be cut off of the bottom?
I have cut my current seatpost down to about 230mm so when its all the way down to the collar it still clears my rear shock (rocky mountain slayer sxc). I just want to make sure that with a joplin I can still have good clearance or even trim a little if necessary.

2. Yes, a little can be cut (maybe 40mm worth)
I'd say the shortest length you can get this with it fully down and cut to the limit is about 270mm, but that's just an estimate and I'm no good at math really.

Do you ever want to put your seat up to climb and down to descend? Bam! Takes the push of a button. I love this thing. Nothing I hate more than clown bicycling up a hill with my seat down and knees in my chin. So if you are like me and enjoy the ride down but like to go up to get some exercise then this is your tool. Yeah I know its expensive and heavy, but so are pedals or a seat and I would not ride without those either. This is the coolest thing ever. Buy one! I ride a 6 intense tracer is 29lbs with platform pedals and this seat post. I have had this post for about 9 months and not a single problem yet.

This seat adjusts 3". THREE INCHES. it might be well constructed and a piece of quality workmanship but 3" ain't doing shitass for me. i ride a lot of hills, my saddle is high for the climbs and then i want to drop in to the cockpit for the ride down. i barely even noticed the change in height on this post. you might be OK with this seat if you ride XC and just want a little bit of adjustment to ride out a bumpy section but otherwise avoid it.
