The Crank Brothers Joplin 4... just in!!!
Building on the success of the normal Joplin, the 4 add an extra inch of drop and an extra guide block to prolong the wobble service interval. A real bonus.
It comes in a variety of models, Lever or Remote and 2 sizes.
You choose which one you need.
post length is 398mm
weight is 505g
adjustment range is 100mm / 4in.
diameters available 30.9mm and 31.6mm
warranty 2 years
An amazing upgrade - it's all about the flow... if you ride steep, techy stuff then you will really love the Joplin.
The minimum insertion is 100mm - just in case you needed to know. Thanks to one chap pointing out this is useful info. |

Average rating:  | Builds on the Joplin '3' and take it to the next leve, 24th May 2010 | Reviewer: Mark Downie | Another TBC real world review for you.
I will keep this one short.
Being a committed uppy downy seatpost kinda rider I already ran a Joplin 3 for a good couple of years - actually find it hard not using one these days.
Anyway - I thought I had better try this out to see what improvements had been made.
For me the key difference is the lack of 'slop' or wobble as it now uses 2 guide blocks to keep it straight in the tube.
The seals have been improved making the service intervals longer and the biggest thing... it's now 4" of drop not 3".
This is useful and I really noticed the difference - sure it's only an inch but it did make a difference to my descending confidence level.
Being a gold finish also made my bike look ace so that is another thumbs up for it.
A definite 'wouldn't ride without' product. |
