eeSilk & eeSilk+ Axle and Bushing Service Procedure

Required Tools

Recommendations and Warnings

 
  • Cane Creek recommends replacing all of the bushing & O-rings during this service so the pivots wear evenly. 
  • Pivot axles must be removed by being pressed out towards the drive-side of the bicycle. 
  • Pivot axles must be installed by being pressed in towards the non-drive side of the bicycle. 
  • Fully service and reassemble one pivot at a time.

Steps:

Remove the Elastomer

Step 1

  • Push the axle (with the pin tool attached) out towards the drive side.

  • Once the axle is removed, lift the arm and remove the elastomer.

Remove the Saddle Clamp

Step 2

  • Remove the saddle clamp assembly by unscrewing the 10mm bolt (Ti thumbwheel on Carbon posts) on the top of the clamp.
  • Next unthread the 4mm at the rear of the clamp.
  • Remove saddle clamp assembly

Remove the Bushing and O-ring

Step 3

  • With the saddle clamp assembly removed – the post is now prepared to be serviced. 

  • Start at the lower most rearward pivot. Begin by using a pick or small screwdriver to lift the bushing out of pivot bore.

  • Next, use a pick or small screwdriver to remove the O-ring that sits centered between the two bushings.

Replace with New O-ring and Bushings

Step 4

  • Replace O-ring making sure it seats completely in the channel within the pivot bore. 

  • Press in new bushings using your hand

  • Only use the bushing and O-rings supplied in Cane Creek eeSilk rebuild kit.

Re-install Axle & Pin Tool

Step 5

  • Reposition the post into its original position (without the elastomer installed). By pushing the arms down to line up the axle hole on the post and the axle holes on the arms. 

  • Using the pin tool as a guide for the axle to enter the axle bore; push the axle into the axle bore on the drive side of the post.

  • Leave the pin tool installed on the axle.  It will be used as a reference as to which side to press the remaining axles in and out.

Install the Axle Pressing Tool

Step 6

  • To install the eeSilk axle pressing tool in the axle removal position – Unthread the grub screw until it is flush with the inner side of the pressing plate.

  • Next loosen the two bolts connecting the two pressing plates till the tool is able to slide over the pivot to be removed.  Insure the grub screw on the non-drive side of the bicycle/seatpost. AXLE MUST BE REMOVED IN THIS DIRECTION (toward the drive side).

  • Move to the arms towards the rear of the bike – Giving you access to the pivot located directly above the axle with the pin tool installed.

 

Press out the Axle

Step 7

  • Once lined up, evenly tighten socket head bolts with a 5mm hex wrench until both press plates are tight against the seatpost. 

     

  • Use a 3mm hex wrench to tighten the grub screw until the axle is removed.

  • After the axle has been removed, unscrew the grub screw and connecting bolts to remove the tool and expose the bushings.

Remove and Replace Bushing & O-ring

Step 8

  • Repeat the same procedure as step 3 and step 4 on this pivot.

Press in the Axle

Step 9

  • With the O-ring and the bushing at this pivot replaced – Push the arms back into position, line up the axle hole on the post and the axle holes on the arms.

  • Place the axle back into the seatpost from the drive side by hand. 

     

    With the axle placed into position, push the arms so that the tool may be installed.

  • Reinstall the eeSilk axle pressing tool in the axle installation position- Unthread the grub screw until it is flush with the inner side of the pressing plate. Next loosen the two bolts connecting the two pressing plates till the tool is able to slide over the pivot to be removed.  Insure the grub screw on the drive side of the bicycle/seatpost. AXLE MUST BE INSTALLED IN THIS DIRECTION (toward the non-drive side).

  • With the pressing tool, pivot, arms and axle lined up – Use a 3mm hex wrench to tighten grub screw until the axle is fully seated into the seatpost.

  • DO NOT use press plate and connecting bolts to press axle back into seatpost, as this could cause improper press alignment.

Service the Remaining Pivots

Step 10

  • Repeat steps 6 – 9 on the remaining two pivots.

  • Continue using the Pin Tool as a reference as to which side to press the remaining axles in and out.

  • Articulate the post to provide ample room for the axle pressing tool as you service the remaining pivots.

  • The lower most forward facing pivot will require one of the axle pressing tool connecting bolts to be removed while installing the tool.

Reinstall Saddle Clamp & Elastomer

Step 11

  • Remove the axle with the pin tool installed and reinstate the saddle clamp

  • Reinstall the elastomer and push the arms back into position

  • Line up the axle hole on the post and the axle holes on the arm. Use the pin tool as a guide for the axle to enter the axle bore, push the axle into the axle bore pin side first.

  • Remove the pin from the axle once the axle is fully inserted into the axle bore.

  • Fasten the 3mm hex bolt back into the axle.Hold the 4mm axle bolt, fasten the 3mm hex

Best part of being a part of the Cane Creek family:  It’s very refreshing to work for a small, tight-knit company where we all share the same passions and to develop new products that make cycling better for everyone.
What you’ll find me doing on the weekends: Obviously riding bikes, but also wrenching on bikes or cars, exploring the mountains, and watching F1 races.
How I got here (at Cane Creek): Feeling pretty unfulfilled with a corporate engineering job, I happened to see that Cane Creek was hiring. I jumped at the opportunity to get my hands dirty working on the latest bike tech and was fortunate enough to be offered the position.
