I like the zebra seat!
thanks
I saw one of Hope’s Ti-pistoned six pot brakes on their stand at a show a couple of weeks ago. They had a demo setup with a brake and a hub for you to try/play with – it looked very nice and it felt really smooth! I mentioned to the lady from Hope that I had quite an unusual application in mind – for a freewheel unicycle – I’m not sure she knew how to process that one 
Anyhow, they are kind of pricey – £1400 for a limited edition presentation set of front and back brakes and vented discs. At that price I think they’d would be staying in the box and going with my limited edition Brooks saddles etc, which is kind of a shame!
Fortunately, you only need one - having lost a wheel has apparently its advantages…
Well yes, but they don’t come individually so you’d need to fit them to two unicycles – maybe one with a Pipifax and one with a Flick-Flock… getting a touch more expensive
And being at that point you’ve got two nice wheels, might as well have one go into a nice Flansberrium frame and the other a Tritao frame…
