Clear the rear
How to remove your back wheel
Unscrew and chock up
With the bike on a stand (main or paddock), undo the spindle nut and place a piece of wood under the tyre to support it at its current height. Then whip out the spindle.
On a roll
Push the wheel forward so that the chain is slack enough to slip off the rear sprocket. Roll the wheel out and away, noting the location of any spacers that drop out when the wheel is removed.
Get it aligned
To refit the wheel, seat the sprocket carrier and spacers then roll the wheel back onto the piece of wood. Then use a 3/8 extension bar as a makeshift spindle as you refit the spindle from the other side.
Tighten and pump
Push the wheel forward with your knee and tighten the spindle nut to the correct torque setting. Spin the wheel to make sure it’s correctly fitted and pump the rear brake lever until firm.
