Yet some insist that chain tensioners are the only way to pedal-power nirvana.
Of course, all the pro road racers had the same issue of wheels pulling out in races until vertical dropouts came to be in the 1970s. Read the chronicles of the Tour de France between 1930 and 1970 and you can see read about races being brought to a standstill by the mass wheel pullouts. (
Send my the links when you find them! While you are at it, send me links to photos of track racers of the 1930s with their tensioners.)
Question: did Nelson Vails use tensioners?
