Q regarding permissible kit, if you don't mind.
1) Top-tube bags: I've heard contradictory tales about this. Some of my club members are "Get the lunch boxes off, they are not compliant". But others disagree. I suppose it comes down to what they are compliant *with*.
2) Front wheel rim depth. I've read about requirements that X percent of the wheel is open. Humm. Is that true, and what does it mean in practice? Is a mainstream Zipp 808 clincher OK?
