Planning a short 2-day tour, just us and a friend. Part of the route gets remote, with a 5 mile section of either freeway, or gravel frontage road. 320 lb team running 28mm gatorskin ultras on rolfs, which is all we have.
We have ridden freeway shoulder (remote 2-lane) on another ride for 20 miles where there were no alternatives and it was doable. I'd take my solo on this gravel no problem but don't know much about tandems on gravel and don't want to get stranded with a damaged wheel or tire. What do you recommend?
