This might be the birth of something epic here? KleinFest UK (sponsored by Autoglym).
Rule 1. Ground must be dry
Rule 2. Sky must be cloudless with no rain forecast for the following seven days
Rule 3. RIGID forks
Rule 4. Twice hourly stop and polish breaks
Rule 5. No mud (dust allowed in moderation)
Rule 6. No rocks/roots/jumps or drop-offs of more than 10mm in order to limit risk of box-fork equipt Kleins cracking
Rule 7. All seatposts must be over 400mm

Please feel free to add more rules
Rule 8. CANTI-BRAKES ONLY
