I've got napkins all over my desk with various designs of stands for both normal swingarm and proarm.
We've been doing a lot of messing around with carbon this year and I think we've found a method of manufacture to make strong and sturdy, yet light weight carbon tubes. More than good enough for paddock stands. I have a one metre length of 25mm tube here than none of us can break. it's a little bit bendy, but we've spoken to the people that know these things and were shown the light with a new two pack epoxy that goes rock hard without being brittle.
They won't be cheap, carbon never is, but if we can just add another couple of hours to every day we should be able to knock something up.
Oh, and yes there was a factory option. It's not HRC, so talk to Andy and he might be able to sort something.
