How To Assemble Your Cairn

At Cairn Cycles we do our best to make sure that there is a very small amount of work for you to do when your bike arrives. In our workshop here at HQ we adjust the gears, brakes and check everything is fitted correctly and set to the required torque settings. However, there are somethings we can not do, mostly to get the bike in a box and to you in one piece. So, we have to remove some bits. This means When your bike arrives follow these quick and simple steps and you will be out on your bike in the time it takes it to charge.

1. Remove your new bike from its box and remove all foam and card packaging. Be careful if using sharp items to remove the packaging so that you don’t scratch the frame.

2. Remove front thru-axle, remove any cardboard packaging, fit the front wheel in the drop outs (locating the disc rotor in between the brake pads in the brake caliper) and then re-fit the thru-axle using your mini torque wrench to tighten the axle up to 10Nm.

3. Place the handlebars in the stem and tighten each of the 4mm bolts to 5Nm using the mini torque wrench. Be sure to tighten the bolts in an X pattern so that there is an even gap at the top and bottom of the stem clamp. When at 5Nm the wrench should look like the following photo:

4. Locate the saddle and Seatpost and insert into the frame, the frame has carbon assembly paste pre-applied – we would recommend cleaning the post and replenishing this paste at least every six months (do not use grease as this may damage the Seatpost/Frame).

5. Put saddle to your desired height and tighten the seat clamp to 4Nm.

6. The last thing to do is to charge your Cairn’s battery, fit your favourite pedals and take it for a spin! We would recommend you fully charge the battery and that you use copper slip, anti-seize or waterproof grease on the pedal threads. Please be aware that pedals are specific to the left or right side of the bike (from the rider’s perspective) and that the left pedal has a left-hand thread.
