Having trust in the quality of your equipment is good, but it’s always best to be on the safe side and check important components at regular intervals even if your road bike is running perfectly.
As the adage goes, “Never change a running system”. This applies especially to the brakes and shift system. If these are working perfectly, then don’t adjust anything. You should, however, regularly check the following components.

Cockpit checks

1. Stem bolts: Use the Canyon Torque Wrench to check the torque of the bolts on the handlebar and fork Picture 1 steerer clamps Picture 2. The torque required is indicated on each component.

2. Check the screws on the crank arms Picture 3

3. Disc brakes: Check if the screws are loose. Tighten them only if they have become loose. Picture 4

Check Headset play

4. Headset play: A loose headset causes imprecise steering and banging noises. This will show you how to check the function of your headset easily: Lift your bike by the top tube until the front wheel is hanging in the air. Now give the handlebar a gentle shove with your free hand as shown. Picture 5 The front end of your bike must swing from side to side under its own weight. Now let the front wheel back down onto the ground. Press on the headset with your thumb and index finger and pull the front brake with your other hand. Now wiggle the bike back and forth and you will feel it immediately if there is any excess play in the headset. Picture 6

This is how you adjust a loose headset:

Undo the screws on the headest. Picture 7 The headset is preloaded by the upper screw on the top cap. A quarter turn is often enoufg to adjust the play in the headset. Turn the screw left if the headset is too tight Picture 8 Re-tighten the screws of the stem. Always mind the correct torque.

You might need to repeat this process until the headset is correctly adjusted. Before you finally tighten the stem scew, the stem must be parallel to the top tube. But the front wheel between your legs and look in a straight line over stem and top tube.

Check further components

4. Quick-release check. Check both the front and rear quick releases. Tighten the quick-releases hand tight. The levers should point upwards when they are fully tight so that they don’t catch on things.

6. Check if the tyres are clean. Small parts might sick in the tyre without flattening it. Remove these small parts from the tyre.

7. The seat post needs fresh greasing from time to time so that it can slide easily inside the seat tube. However, it is important to clean both the seat post and tube thoroughly first. First remove the seat post and wash the grease off with a cloth. Then clean the inside of the seat tube. Try to get down as far into the tube as you can with a cloth. Picture 9 Now apply fresh grease paste to the seat post.

DANGER: If frame or seatpost are made of carbon, do not apply grease! In this case, use carbon assembly paste! Carbon parts must be free of oil and grease at all times.

8. Check the drain hole under the bottom bracket. Picture 10 This place is exposed to dirt. The result: condensed water can not leave the frame. Clean the hole if necessary. Use a long, pointed object to do this made of plastic. Metal obects could scratch the frame.

9. The pulleys of the rear derailleur are liable to become dirty as well. Clean them if necessary using acloth pulled over a screwdriver. Hold it against the pulleys and turn the cranks. Picture 11

10. If the chain rattles or is hesitant in shifting onto the next sprocket, then this is most probably caused by a slightly stretched shift cable. This often happens to road bikes after only a short period of use. You can, however, remedy the problem in just a few seconds by slightly adjusting the tensioning bolts (turning anti-clockwise) which are fitted on the gearshifter attached to the handlebars. Picture 12 Warning: Only adjust the shift system when it is really necessary. If it isn’t broken, then don’t fix it!

11. In order to achieve maximum performance from your bike, the chain should always be kept clean and well lubricated. Clean your chain by pulling it through a clean cloth and then lubricate it. Ensure that every link gets sufficient lubrication. Let the oil briefly soak in and then remove excess oil with the cloth.Picture 13
