Chappelli Bicycle Maintenance Manual v4.0

12. Ongoing maintenance & repair of your Chappelli Cycle

Break-in Period

Most bikes require a break in period before riding them ‘hard’. On Chappelli Cycles there is less that can go wrong because they don’t have gears. However you should still avoid long rides for the first few weeks of riding and make sure that you check the chain tension after a few weeks as the chain links will stretch with use. It is a good idea to give the bike a thorough check over 1 month after purchase to make sure everything is still securely attached and nothing has come loose or need re-adjustment.

Tyres

Tyre pressure should be checked regularly to ensure the tyres are correctly inflated. The tyres should not be inflated over the recommended maximum.

Chappelli Cycles tyres have a Presta or French Valve which has a narrow diameter and is only found on bicycle tyres. Most bicycle pumps will have a head designed to fit a Presta Valve however car pumps at service stations will not and so you will need to use a proper bicycle pump.

To inflate a tyre fitted with a Presta Valve first remove the cap and then unscrew (counter clockwise) the valve lock. Push down on the valve stem to make sure it is open. Then apply the pump head and inflate the tyre to the desired pressure.

To convert tyre pressure from pounds-force per square inch (PSI) to kilopascals (kPa) use the table below:

PSI kPa PSI kPa
50 344.7 110 758.4
60 413.7 120 827.4
70 482.6 130 896.3
80 551.6 140 965.3
90 620.5 150 1034.2
100 689.5 160 1103.2

Brakes

Brakes need to be checked before every ride – see Section 9 Getting Ready to Ride. The easiest way is to squeeze both the front and rear brakes and try to move the bike back and forward. The wheels should be locked and everything should feel tight. If not, then you may have a loose headset or the brake-pads need adjusting. If you have any doubt about this, you should take the bike to a licensed mechanic to check properly.

Brake blocks (or pads) should be replaced when they are worn or uneven. This should be done by a licensed bicycle mechanic.

Cleaning

After a long ride or if the bike has been exposed to rain or salt water it should be cleaned and the chain and moving parts lightly oiled.  To clean your Chappelli Cycle you should use lightly soapy water and dry with a cloth. You can use this to clean the rims but please do not use any solvent or oils on the rims as this may interfere with the brakes making them less effective and potentially putting you in risk of harm.

Lubrication & Oiling the chain

To keep you Chappelli Cycle running at maximum efficiency it is recommended that you regularly lubricate you bicycle.

Your bike chain should be lubricated at least monthly. This should be done by lightly applying a bicycle lubricant along the length of the chain whilst rotating the chain slowly. Make sure you wipe off any excess with a cloth and please don’t do this inside on white carpet (I learnt the hard way)

Brake calipers can also be lightly lubricated however keep any oils away from the brake pads. Brakes cables, levers and calipers should be lubricated every 3 months or so.

Rust & Corrosion

To avoid rust and corrosion it is recommended that you:

  • Store you bicycle in a dry area away from dampness or wet air
  • Do not leave your bike outside in the rain or exposed to salt air
  • Clean and oil your bike after any exposure to rain or salt water
  • Warning: Beach areas particularly in Sydney have high salt air content which will cause rusting to your bicycle. Applying WD40 will help slow this down by limiting moisture penetration.
  • Warning: Rust or corrosion is not covered by the Chappelli Cycle warranty

Handle bar grips and tube plugs

Warning: Handlebar grips and tube plugs should be replaced if they are damaged or worn. Naked tube ends have been known to cause serious injury in the event of an accident. This is particularly the case for bicycles ridden by children.

Assembly and ongoing maintenance – Use of a Torque Wrench

If you make any adjustments to your bicycle we recommend you use a torque wrench and adjust to the following torques for parts of the bicycle.
