You should take your cycle to a cycle shop every year to have it serviced but there are many checks that you need to do yourself throughout the year. You can VIEW some basic maintenance advice if you click here or for more detailed information by clicking here. The latter video is specific to MTBs but its generally good advice that can be applied to any bike.
We would suggest that you check your cycle according to our summary below:
Every time you use your bike have a general look to see that it is in good condition, that things are tight, & pay particular attention to the tyres & ensure they have sufficient pressure.
Each week you should lubricate the chain & pivot points of the front & rear gear mechanisms.
Take care not to get any lubricant on the wheel rims or brake pads.
Each month we would advise that your perform the following checks:
Brakes - Check the brake pads for wear and ensure that they contact squarely with the rim, not the tyre.
Cables - Replace any worn or frayed brake cables and adjust brakes as set out above. Lubricate new cables at the points they contact the outer housing.
Chain - Clean in accordance with the Bike Cleaning section below & re-lubricate.
Cranks - Check each pedal arm is securely fixed to the axle in the bottom bracket by pulling hard sideways. If there is any movement you may need a specialist tool to tighten the crank to the axle or have problems in the bottom bracket so consult your cycle shop.
Frame - Look over the frame for any damage. Ensure that the saddle height is correct and that the seat post bolt is tight.
Gears -Check gears work correctly and cables move freely. If the shift isn't smooth or doesn't engage the sprockets accurately, i.e. the chain makes a clicking noise when pedalling, take your bike to a cycle shop for adjustment.
Pedals - Pedals should spin freely so check the pedals for looseness on the shaft they are attached to - if there is too much play the bearings may be worn & require the pedal to be replaced. Check this by holding the crank firmly & moving the pedal from side to side. Replacing the pedals is easier than replacing the bearings but you can do this if you have sufficient experience. Check the pedal is securely attached to the crank and tighten as required. See also the section above on pedal replacement. Consult your cycle shop if problems persist such as clicking as you rotate the pedal whilst riding.
Steering - Check for any looseness in the handlebar and stem, relative to the frame, and tighten as required. An allen key is normally required to tighten the stem.
Wheels - Check the tyre pressure, inflate as necessary and check the condition of each tyre. Check the wheels are tightly secured to the bike and that they rotate in line with the frame. Have a look to see if you have any broken spokes. With the cycle lifted slightly off the ground try to move each wheel sideways to check there is no movement against the bearings in the axle. Wheel repairs are usually best done by your cycle shop.
