Double chainring setups from the French touring era rarely survive with both rings intact and the pedal thread still clean. This SOLIDA unit keeps its 40-50T combination on 170mm arms, with a 14x1.25 French pedal thread — the standard that Peugeot, Motobécane and Gitane frames of the period used throughout.
What makes this SOLIDA double chainset worth fitting
Steel construction, two chainrings, and no oxidation reported on the unit. For a touring bike or randonneur-style build where the original gearing needs to be replaced without drifting into modern components, a 40-50T double keeps the ratios period-appropriate and avoids the chainline guesswork that comes with mixing eras.
The 170mm arm length is the common choice on vintage French frames of this generation, and 14x1.25 threading means standard French pedals thread straight in without adapters or re-tapping.

Matching the thread before you buy
French-threaded pedal cranks are the specification most often mixed up with British or Italian standards. The 14x1.25 marking is the direct identifier here — cross-check it against the bottom bracket shell on your frame before committing. If you are also refreshing the bottom bracket at the same time, a Shimano 600 EX bottom bracket, 116mm BB-6207, 1.37 x 24 TPI is the kind of period-adjacent option that pairs with a French-threaded crank without forcing the chainline.
For builds leaning toward lighter chainring configurations, the range also includes a SOLIDA Motobécane single/5-speed chainset, 46T, 170mm, French thread 14x1.25, which uses the same thread standard on a single-ring layout.
