Official Rules 10, 11 and 12

10. Any colour of bike is acceptable, but overly prominent logos, world championship stripes or customised rider names are not desirable.

11. While a lighter bike is beneficial, the Scottish Cyclist should not pay too much attention to its weight. This is partly to ensure maximum durability to withstand the harsh Scottish conditions. The Scottish Cyclist should overcome any drawbacks in equipment quality through fitness and skill.

12. Wheels shall be equipped with clincher tyres. The propensity for punctures on the rough Scottish roads rules out tubulars. The risk to puncture a tubular miles from home is too great. However if the Scottish Cyclist can effectively fit tubulars, this is a useful skill. See rule 8: Performing your own maintenance.
