HOW TO CHANGE AN INNER TUBE WITH TOTAL WOMEN'S CYCLING @TtlWomenCycling
If you get a puncture while out on your bike, it’s quicker and easier to just replace the inner tube, rather than faff on trying to patch it up. From experience, we’ve found it’s never a wise idea to wait for a puncture; it’s best to practise the technique at home. Some tyre and tube combinations can be quite tight, needing thumbs of steel, don’t give up, persevere and you’ll get there in the end.
Tools needed:
2 x tyre lever
1 x mini OR floor pump
1 x new inner tube
Inner tube: Separate inflatable tube that goes inside your tyre.
Presta valve: Type of valve on inner tube. A thin valve, with screw-in tip, means high pressures can be achieved and maintained.
Schraeder valve: Type of valve on inner tube, also the same as found on cars. A wide valve, predominantly reserved for mountain biking, with a pin in the centre to release air.
Quick-release wheels: A mechanism that allows you to remove wheels without the need for tools. A skewer runs through the axle, with a lever one end and nut the other.
Spokes: Thin poles or blades on your wheels that connect the rim to the hub.
Spoke nipples: Special nuts usually found connecting the spoke to the rim. It helps to adjust the tension of the spoke.
Lock ring: A ring that screws on the threads of the inner tube valve. Once the valve has been inserted through the rim, the lock ring holds the valve in place, preventing movement.
Rear derailleur: A mechanism that moves the chain between sprockets to give a range of gears.
Sprockets: Toothed discs that the chain run on to drive the rear wheel.
Bead: Metal or Kevlar wire found in tyre. Holds tyre to the rim.
V-brakes: A brake that acts on the rim. V-brakes have two nearly vertical arms that mount on pivots on the frame and are pulled together with a brake cable across the top.
Rim: Outer part of the wheel, where the tyre mounts.
