Riding “up”
Basic principle (always refer to this): you can’t ride “down” – some people can ride up, but you can “never” ride “down” (downhill in the below diagram).
Note that this document is meant as an easy quick reference. If you want to read the rulebook go to: Rulebook for Australian Events (Rule 006). 
This diagram applies to Challenge and Cruiser Categories. You can’t ride “up” into Superclass or Elite Categories.
Rules of the “Class”
When you ride up into a class, you are subject to the rules that apply to that class, not the class you came from.
Basic principles:
- “riding up” means moving “uphill” in this diagram
- You can only ride "up" 1 age classYou can never ride “down”, so you can’t move down the line in this diagram
- You can ride in the opposite gender of same age or 1 age higher - a 15-year girl can nominate in 16 boys if she's game. A 16 boy can enter in the 16 girls if he's game
- 8-year-olds are restricted to 8 year class. Boys can enter in girls class, and girls can enter in boys class, but they can't "ride up" at all.
- Sprockets ... you can't ride out of sprockets - yes a 5-year can enter the 6 sprockets (only riding up 1 year), but a 7 year sprocket can't ride up into the 8s. Sprockets are stuck in sprockets until they are not sprockets.
Example 1: a 16-year old rider wants to ride against his / her mates in 17-24 – no worries, he they can “ride up”
Example 2: a 3745-year old rider thinks he’s they are superman and wants to race against his younger / her younger mates. He They can ride “up” (uphill on the diagram) to the 3017-34 24 class, but can’t go to a younger class than that
Example 3: A 3317-year old rider wants to ride with his mate in 17-2416 boys. He cannot ride that class because he that would be riding “down” (going downhill on the above diagram). Note that However his mate can only ride "up" nominate to ride “up” into the 25-29 class (ride up 1 class only)17-24 class.
