CHAIN TENSION

YOU WILL NEED:

10mm 19mm 22mm

Stool or Degreaser Chain Old cloth work stand lubrication or rag

ALSO USEFUL

1. First, make sure that the power is turned off.

2. Secure your bike on a stool or stand, and loosen the bolts on the rear wheel (it is unnecessary to remove them); the drive side bolt is 22mm, and the non-drive side is 19mm.

3. With a 10mm spanner, adjust the bolts shown in the picture below to move the wheel backwards to tighten the chain; it is important to remember to do this equally for both sides; otherwise, you may misalign the wheel.

Small changes can have a large effect, so do this in small increments.

The chain should be taut, not tight; overly tight is just as bad as loose.

When a little pressure is applied, the chain shouldn’t touch the frame

4. This is a good time to clean your chain; apply the degreaser and work into the chain with your cloth; gently wash off with water, DO NOT use a pressure washer; this will force water into bearings and hard-to-reach places and may damage your chain.

Once you have applied lubrication to your chain, wipe off the excess.

Before you finish, please ensure your wheel and chain are straight before tightening the bolts.

WARNING

Failure to maintain and adjust the chain and align the wheel correctly could result in the chain jumping off the sprockets, causing a potentially dangerous and damaging situation.

Please open the QUICK START GUIDE attached to your bike; you should find the serial number there.

The serial number will also be on a label on the side of the box your Kuberg bike was delivered in.

If you no longer have either of these, you will also be able to find the serial number on the head tube of your bike, it can be slightly difficult to find in low lighting.

The VIN is stamped on the right side of the steering head tube, located at the front of the frame, just below the handlebars and above the front wheel.

To locate the VIN, you may need to turn the handlebars to the left or right and look closely at the steering head tube for a series of numbers and letters that make up the 17-digit VIN.
