Well BV have responded to my concerns.
Looks like I'll be risking the transport..
Hi GREMlin - please don't be concerned! I have just updated that page (http://www.bv.com.au/great-rides/30144/
) - one of our team members wrote it very quickly when the new site was being posted, and I have just been reviewing all of the changes.
It is not at all necessary to bring a bike box. In my experience, the vast majority of riders in the 100km do NOT bring their bike in a box. Apart from anything else, it causes a huge amount of waste in Sorrento! And the term "cattle truck" is not at all appropriate, I apologise for that. It is a term some of our events team may use "in-house", but in no way reflects the type of transport you will experience on the day.
Please be completely assured that both you and your bike will have a smooth and comfortable ride to Sorrento.
I apologise for the concern - completely understandable given the information you read, but consider this information REDUNDANT!
