Bike Maintenance Tips
The Pre Ride Inspection
The best defense against loose components is a thorough pre-ride inspection before every ride. Regular pre-ride inspections will help you catch potential problems before they develop into safety hazards. Most pre-ride inspection adjustments can be made with a simple bike multitool.
This involves conducting a safety check of all the main working parts of a bike and with practice, should take no more than two or three minutes.
It’s called the ‘M check’ because you should work from the front of the bicycle backwards in an M shape to make sure you don’t miss anything.

Tyre wear - Check visually that tyres are not split or cracked and that there is tread remaining on the tyre.
Tyre pressure - Check that tyre is firmly inflated to the recommended pressure on the tyre wall.
Hub bearings - Grip the wheel rim and rock back and forth to feel for loose bearings; spin wheel to check for over-tight bearings.
Rims and spokes - Check visually for any defects, and spin wheel to check that it runs true.
Brakes - Check angle of levers and that they can be comfortably reached. Brakes should apply pressure at 1/3 to 1/2 of travel.
