I. Thou shalt hold no other races above the Tour de France.
II. Thou shalt not make unto thee helmets which cost more than £100.
III. Thou shalt not take My name in vain everytime thou gettest a flat tyre.
IV. Remember to oil thy chain, to keep it rolling.
V. Honour the Zebra Crossing and those walking upon the face of it.
VI. Thou shalt not ignore other road users, nor cycle recklessly upon the pavement.
VII. Thou shalt not steal bicycles.
VIII. Thou shalt not kill, except bicycle thieves.
IX. Thou shalt not hang onto moving cars.
X. Thou shalt not covet they neighbour's new Cannondale, nor his groupset, nor his £3000 mtb, nor even his stylish shades.
Forget not the Titanium Rule: Signal unto others as thou wouldst have others signal unto thou.
