Thanks for the reply
Thats the problem here in Aus they get stuck in the technicality and forget the fun and its a hoby bit
Obviously at top level (NSW CHAMPIONSHIP) it might mater in some classes and some freedom would invite more people into it
BTW these solarus tyres ..how good are they
we run ryde or muchmoore 28-36(yep it about 10c in Australia on a friday night)
All the best
