Description:
A legendary French headset benchmark, the Stronglight Competition was the standard of excellence across the professional European peloton for decades. Renowned for its micro-ground, glass-smooth bearing races and robust sealing architecture, it withstands punishing road vibration while preserving razor-sharp steering precision. Built strictly to French metric 25 x 1 mm threading with a 26.5 mm crown race, this headset is an authentic, mechanically superior choice for vintage French steel frames from Mercier, Gitane, and Peugeot.
