Product Description

The model 49 / 49D crank was introduced in 1949, and ran until the 80's with only minor changes.  This very clean example is an early model from the 1950's or possibly very early into the 1960's. It's identified as such via the lack of any words on the back of the crank arms themselves, having "49D Made in France - 170" on the arm heads only.  They also have deeper flutes with a more gradual taper to the depth than the later ones who's flutes have a more flat and smooth bottom.  This one is made specifically for French frames, as the pedal and BB threads are both French.

This has been "upgraded" with TA Pro 5 Vis chainrings and TA-373 bottom bracket spindle, as well as Velo Orange chainring bolts.  It is quite common to see earlier 49D cranks with TA rings, due to TA producing lighter chainrings with much wider tooth counts available than Stronglight did in the era.  Original 49D chainring bolts were soft alloy 8mm nuts that were easy to strip, and the VO bolts solve that problem by using modern 5mm allen heads.

Condition

Near mint very lightly used shape with low miles!  These are show bike worthy!  The arm ends are just barely scratched in spots. Arm fronts and sides have only light scratches, none that are bad enough to mention.  They're not pristine, but they are very clean.  Chainrings are very close to mint and show no real wear.  Chainring bolts are new. 

Bottom bracket cups look almost pristine with just very light microscratches in spots.  Tapers show very few marks.  Drive-side cup does show the lightest scuffing inside the cup, but when I pulled these from a show bike they spun buttery smooth without a hint of drag/grit/pitting.  I was surprised to see these marks after feeling how smooth they were.
