FeK9 Posted August 12, 2013 Share I would pay serious money for a retrodrive like that. Pedalling forward engages one rear cog; pedalling the other direction engages the other cog. So you get two ratios, one for flats and one for hills. Back in those days, your only other option was to flip-flop your back wheel, with a cog on either side. Nature know's best...
