Helpmytrap Posted August 12, 2013 Share not sure that would workIt wouldn't at all because the chain will run at different speeds over each cog and in opposite directions BUT if the bigger cog spun freely it would work. Link to comment Share on other sites More sharing options...
DawieO Posted August 12, 2013 Share not sure that would workFreewheel in 2 different directions, means you can produce power pedaling forward AND backward. Link to comment Share on other sites More sharing options...
Myra Posted August 12, 2013 Share I am yet to find that same instant satisfaction in cycling, nothing beats the feeling when you are 150-200m off the ground and you manage to hang onto that tiny sliver of a "ledge" and make it to place the next cam / nut etc. You need to do bigger drop offs.

Hairy Posted August 12, 2013 Share Average 13.48 kays an hour. That's my pace Let's not forget that the rider surely stopped to take care of natures call and hopefully get some sleep in the 89hr ride ... so that average speed or rather average riding speed should increase dramatically once the above have been considered.

LeTurbo 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.
