<------------------ SOLD ------------------> Stronglight model 200 chain ring - 50 tooth - 122 mm BCD (NOS)

Stronglight chain ring - 122 mm BCD - aluminum alloy - 50 tooth - model 200-50 ... [NOS - suitable for use with cranksets having a 122 mm Bolt Circle Diameter (BCD) such as Stronglight models 49 (...inner ring only), 93, 104, and 105 or various late series production 1980's Nervar cranks - 50 tooth chain rings such as this one are perhaps best used in either a fixed gear application or in setting up a vintage version of a "compact double" crankset (...38/50, 40/50, or even 42/50) - Stronglight 200 series components also offer an excellent alternative to the pricy and often difficult to source original model 93 or 105 chain rings]
