Wow, what a minimalist achievement! I'm maximally impressed.
Glad Sean survived his prang. The whole project is a very good advert for Mercury + Rohloff, for sure.
Impressive trick gear, too: I thought I had some lightweight stuff, but this is at another level of barely-noticeableness.
I tried a larger version of his ultra-light Klymit, but found it didn't work for me. Then again, I'd guess I'm 40 lbs heavier than Sean. Not sure I'd fancy riding across Canada without some decent bug protection, either -- in the form of a mesh tent inner, not lotions. But he mentioned riding in warm countries.
No fenders/mudguards -- a problem in rain & mud? Less of an issue in Oz and similar, I guess, but in a tropical rainstorm on a dirt road?
Thanks for posting this, Anto -- I hadn't heard of his great adventure.
