It appears that only the cat 1 and 2 riders need worry during the season but I would guess that for the provincials you will need smaller tires.
Last couple seasons they have allowed disc brakes for example and mountain bikes too for the lower cats during the season but not for 1 and 2 and for no one at the provincials except and please correct me if that's wrong for the beginer cat at the provincials. That was because there is no provincial beginer champ crowned.
And I am starting to train on the cross bike on the North Shore a bit if you wanna tag along, I'd be happy to train with someone.
Debate? Bikes are made for riding not pushing.
