Kiwi Pete,
Wow, now that is a bike and a half! I thought my Nomad was over engineered, but it hasn't got anything on this bike.
Not even I would be worried about being too big to ride this. I'd be a little nervous riding the one in the background though.
Less than 10km to go and 5000km on my Nomad and just one puncture in all that time (and a front one, not rear.)
