Parts OneUp Components Dropper Post Travel Adjust Shims – 3 Pack

Want the longest travel dropper that you can get? 150mm is too small for your liking, but 170mm won’t fit?  These shims can be installed in your V1 OneUp Dropper Post to adjust the amount of drop.

It can all be done with the post on the bike, without tools, and without removing your saddle. Genius!

170mm posts can go all the way to 120mm, and 150mm’s can be slammed down to 100mm.

INSTRUCTIONS

1. With no shim installed, lower your fully extended post into your frame as far as possible. If the post bottoms out inside the frame before the post collar hits the seat clamp, wrap tape around the lower tube just above the seat clamp to mark the height.

2. Unscrew the post collar by hand and slide it up towards the seatpost head. Then gently press the remote lever to pop the upper bushing (White part) out of the lower post. Then slide this bushing up towards the seatpost head

3. Drop your saddle to a mid-stroke position at least 75mm below full extension. Install the full 50mm shim by sliding it into the lower tube below the upper bushing, legs down. The middle leg should be lined up with the laser markings on the back of the post. Each leg will fit into a groove inside the lower post.  Gently wiggle the shim until it engages each groove and then slide it fully in.

4. Lower the upper bushing and ensure you can push it fully into the lower tube by hand (if you can’t you may need to drop the seat a bit more). Reinstall the seat collar by hand. Extend the post fully. Your post is now 50mm shorter.

5. Raise your entire post to a comfortable ride/climbing height and pedal around in your riding shoes/kit to make sure it is correct. There will now be space between your seat clamp and post collar.  This is the length you will cut off the shim to maximize your drop height. Measure this with a ruler, or if you have an extra shim you can mark directly on the second shim.

6. Unscrew the collar and gently extend the post to raise the bushing and remove the shim. Trim each leg of the shim by the amount identified above. i.e. If there is 23mm between the post collar/tape and the seat clamp, cut 23mm off the shim legs. Make sure you cut each leg to exactly the same length.

7. Drop the seat to a mid-height position at least 75mm below full extension. Reinstall the trimmed shim below the bushing. The shorter shim will be slightly more difficult to install. Use the upper bushing to help push the shim down and if needed use a plastic zip tie to realign the shim inside the lower tube between attempts to fully install it. Make sure the shim and bushing can be fully installed by hand before lowering the seat post collar.

8. Reinstall the seat post collar and tighten by hand. Using the remote fully extend your post. Then lower the extended post into the frame until the post collar or tape touch the seat clamp.

Congratulations, you now have the longest dropper post that will fit on your bike!
