One of the products that really revolutionized my mountain biking was a Crank Brothers Joplin adjustable seatpost. When mine broke recently and had to be sent back for repair I was shocked how much using a rigid seatpost negatively affected my ride.
When Sharon decided to get a mountain bike I figured she needed to have an adjustable seatpost on her bike as well so I moved my Joplin 3″ seatpost over to her Santa Cruz Nomad.
I looked at the Crank Brothers Joplin 4″ travel seatpost, but I wasn’t confident I wouldn’t experience the same failure that I had with my Joplin 3″ post. I had read some good reviews for the KSi900r 5″ post and I found a local source in Calgary [Western Motorsports] that was selling them for ~$220cdn – a much lower price then the Joplin. I decided it was worth trying a KS post and seeing what I thought.
Installation of the post was a breeze with the remote lever and cable coming preassembled in the box. The saddle mounts with two bolts which took a little longer to deal with than the Joplin’s single bolt setup, but I don’t swap saddles often so this isn’t too important to me.
Note the cunning use of a zip tie just above the seatpost QR to keep the remote cable away from the rear tire.
The Kind Shock remote lever [red component in photo above] isn’t as easy to use as the Joplin’s lever, but it’s not awful. If I don’t love it in the long run I can replace it with a Joplin remote lever since the post itself doesn’t care how you pull the cable.
I’m looking forward to having 5″ of travel with this post vs. the 3″ my Joplin had available.

I’ll be even happier if this post is still working fine in a couple years…=-)
