Sports class regulations

At the end of the day it is up to the class as a whole to decide who is in and who is out - democracy in action!
Most of the rules have exceptions - I have used disks front and rear on a bike I both raced and rode to work on, someone living in a flat area might have no need for gears that allow for a 10% standing start, etc..
If you think someone isn't playing fair eg. G. Obree on a PDQ then by all means exclude them, though politeness would be nice.
In extremis I (or MikeB if you want to really make a point!) will make a final decision, if necessary, but I can't see that being an issue.
One thing I've just thought of: if a rider starts racing in the sports class and gets the bug bad and goes out and does TRAINING seriously to the extent that they start wiping the floor with the rest of the class, what do you do? My view would be to let them finish the season as Sports class but exclude them the following season. You wouldn't want to automatically exclude the winner but there may be good reasons to in certain cases.

Well no actually - I was being hypothetical even though it doesn't look like it!

Now that you mention it though....
