All bikes require attention at some time whether you use it regularly or not. If you do not use it, it probably requirements more attention than if you do, but if you do use your bicycle much some aspects will require attention as well. In this article we will discuss some bicycle tune up tips that should put you ahead of the competition.
The first thing to check is the chain. If the chain is not correct, it will not convey all your leg power to the wheels - it will become inefficient and you will have to pedal harder. Not only that, but if the chain is not right, it can wear down the teeth on the cogs and they are much more expensive to replace than the chain.
So, test the tension of the chain by jiggling it up and down from its standard place. It ought to move around a centimeter (less than half an inch) up and down from standard. If it is more than this, slacken the wheel nuts off and tap the wheel back to improve the chain tension. If the wheel will not go back far enough, you need a new chain. Chains do stretch over time.
Next, check the bearings in the pedal hoousing. Do this with the chain off to reduce ambient noise. Turn the pedal arms and wiggle each one from side to side. Listen and feel for friction. The arms ought to not move from side to side at all, although the pedals might.
If the bearings are simply dry, shame on you, oil them, but if you have let it go too long and some bearings are damaged, replace them.
Take the wheels off and holding each one in turn by its spindle, spin them. Listen to the bearings in the hubs. Do they sound OK? Oil or replace the bearings. With the wheels in position, put the front wheel between your legs and hold it tight between your knees. Rock the handlebars from left to correct and back again a couple of times. Is there any play? If so, tighten the locking nut, oil the bearings or replace them.
Check your brake handles and cables. Replace anything that is cracked, fractured or showing signs of rust. Check your brake pads. If they are worn out of shape, replace them and fit new ones so that they will wear more uniformly.
If the pads are deformed then they were not installed properly so your brakes were not working well for a time which means that you were lucky that you did not require them in an emergency situation.
When the brake pads have been fitted properly, recheck the tension of the cables operating them. Tighten or slacken them as needed.
If you are still growing, check the height of the saddle and raise it if needed. If you have stopped growing upwards, check that the saddle nut is tight enough to hold the saddle in place even if you hit a pothole.
Last but not least, make certain that your lights and reflector are working.
