Labor was the first in France to introduce the reinforced frame, the bridge model. It was later copied by many. This racing bike is completely original and in its original paint. It features a beautiful head tube badge depicting the bridge frame. This bike also has a hook at the rear of the frame to hang the chain (so it doesn’t drag in the sand or on the ground) when the rider flips the wheel to shift to a different gear. Regular bikes did not have this hook.
