Follow the video and steps below to install your Canadian made NSB idler. These steps work for either the Stainless Steel or Aluminum idlers on either the Druid or the Dreadnought.

Step 1

Flip open the upper E*Thirteen chainguide and remove the chain. With your 5mm allen key, remove the screw holding the idler in place. Be aware that the shaft is keyed into the back of the upper swingarm/ seatstays and you’ll want to make sure it remains flush in its housing as you unthread the screw.

Step 2

Carefully remove the idler along with the rear spacer and with a cloth, wipe down and clean off any dirt, grime and old grease. With the NSB idler using a solid lube bearing, there is no need to add grease when you install the new idler.

Step 3

You’ll see the idler comes with a flangeless spacer which will replace the stock labyrinth spacer. Place the flangeless spacer over the shaft and slide the new idler on. 

Make sure the retaining clip on the bearing is facing outwards. 

Step 4

Reinstall the idler double ensuring that the shaft is sitting flush in the upper swingarm/ seatstay – we strongly recommend keeping a finger on this as you tighten the screw. The torque value for the idler mounting screw is 10Nm.

Step 5

Reinstall the chain and take note that the idler has narrow/wide teeth so you’ll have to orientate it to the corresponding links in your chain. Close the E*Thirteen upper chainguide and give the system a final pedal to ensure everything is working smoothly.
