Replacing the inner tube
Remove the wheel from your bike and then
remove the dust cap from the tyre valve.
1. Push a tyre lever in underneath the outer tyre.
2. Push the tyre lever upwards to pull the outer
tyre over the wheel rim.
Push the Gtech tool into the tyre valve to
let out the air.
You may need to push down on the tyre to help
remove the air, whilst still pushing down on the
tyre valve.
You will need a 700C x 35/43c inner tube. These can be ordered at www.gtech.co.uk or can be
purchased from good bike shops. If changing the tyre at the same time, you will need a 700 x 38C
tyre. You will also nd it easier if you have a tyre lever handy.
