I agree with Maggie and Sticky. The important people here are the riders. If they don't like it they will say so and not enter. It is my information that they were consulted and want it. The fact is that they voted with their wheels as far as these classes on the mountain course was concerned and didn't turn up, in their droves.
I have already heard of a couple of new bikes purchsed, and they will be there. If enough people buy new bikes or start racing what they've got who knows what the next stage might be.
In the meantime, I for one will really enjoy it. Safe riding folks!
