When Stronglight introduced the 57 crankset, it was available either as a pair of cranks or as a right crank only as an "upgrade" for a 49D crankset, the left crank being nominally the same. It is therefore likely that there are a number of mismatched cranks running around that have been on the same bike for years.
One wonders what happened to all the 49D right cranks that became redundant.
Damage to either crank would be an additional reason for mismatched cranks.

Maybe my eyesight is going, (along with every thing else) BUT The Chain ring crank say DEPOSE and left side says MARQUE DEPOSSE! Is this correct for a 57. But a BEAUTY to behold. The frame all the talk is about has like the old Raleigh 1940s ish that I started out racing on, A VERY relaxed head angle the top tube slopes upward from the seat tube, Norris sent the link to the photos of the TDF Yellow bikes in the 30s and that bike also has the rear brake mounted the other side along with a tyre sweep,like the frame in question, WHY? Seems to me would promote brake shudder. John Crump OldbacktosleepBrit. Parker, Co USA
