Interesting, thanks @hamrack and @amey. I'm awaiting the return of my commuter from paint/frame mods and need to decide how I'll carry my work stuff when I build it up again. I'm swithering between a small pannier on a tubus fly, or something akin to @amey 's
Probably just strapped to the integrated decaleur. Would be very interested if @amey has come up with a good way to strap it to the platform though.
