damion75 0 #1 May 29, 2004 I had always planned to sidemount my new PC109 on my Z1 Evo, but having just tried out a few camera dives using the Centre's Bonehead with chincup and sidemount I am pretty sure that I would like a camera helmet with a chin cup for that added stability. I notice that the adverts claim that the bonehead chin cup can be fitted to 'most open face helmets' but the cheek flaps on the Z1 Evo do not extend very far down.... What I really want to know is if anyone has done this / tried this? Or if I should cut my losses, flog it and buy something else!
