DIY Joplin Adjustable Seat Post Conversion

Got a Crank Brothers Joplin Adjustable Seatpost, that I wanted to convert to a remote setup and I didn't want to spend the money they were asking for the kit, so...I built it myself!

I bought the Joplin Seat Post off Trade Me for $50.00, so the first step, was to strip it and replace the worn parts, clean and reassemble.

Reassembled and tested...all set for modification to take DIY remote.

I wanted to make it an internal mechanism, so that dirt couldn't get in. I cut a slot into the front of the post, to accommodate the lever I was making.

Rear view of slot.

Small lever manufactured & ready for install.

Lever installed.

I had drilled a hole to allow for cable, making sure I aligned it with the lever.

Made up a boot out of an old tube, to keep out the mud.

Made up a remote trigger out of aluminium off-cuts & an adjuster off an old derailleur.

Installed...works perfectly.

Installed trigger.

DIY SRAM Shifter Mount

I purchased an SRAM X7 10 speed shifter for my Foes Fly, & I needed a mount, so instead of paying for one...

Marking out & cutting.

Cut out, ready for weld.

Clamped for welding.

Welded & ready for finishing/filing.

Finished & mounted.

Cost to make, materials...nothing, was from scrap aluminium, labour...about 2 hours, it would've been easier to buy, but then I wouldn't have a one off SRAM X7 Shifter Mount.
