KNOW YOUR BIKE

Essential know-how from mechanic and owner of teamwallis.com

Martin Wallis, NAME BLAME

I always fit tyres with the makers name above the valve hole. This makes it easier to find the cause of a flat. Remove one side of the tyre, checking carefully with your fingers for the object that caused the misery. Remove the cause; a small pin or an Allen key on a multitool is best. When removing the rear wheel, select the smallest sprocket and chainring to make it easier to replace the wheel once the puncture’s been fixed.

CHAIN TRAINING

Always carry a chain tool and joining link. You can practise repairing a chain on an old one, remove the broken link and connect the chain up again, ensuring both ends are a hole, not a pin. Connect the link, then pull! If it won’t make the connection, put the brake on and pedal one side until it does. You can get home with two joining links, but I would replace the whole chain when you get home. Broken chains are usually due to wear or incorrect fitting.

SIMPLE SAFETY

A pre-ride safety check could save you from a fall. Start at the back wheel by checking the tyre, rear quick release or nut. Check the condition of the gear cables and chain. Check your rear brake cable and blocks, and make sure the wheel spins true. Next, give your pedals and cranks the once over. Make sure the saddle is at the right level and height, and the saddle and seatpost clamps are tight. At the front check the handlebar and stem clamps, then take a look at the front brake cable, blocks and front wheel’s trueness and quick release or nut.
