Perhaps better known as Randonneuring in the USA, AUDAX shifters are built for the loooooong haul. Our original and simplest RETROSHIFT friction only shifting system. When you are riding alone and unsupported with no pretensions of racing and understand that a steel frame is worth its weight in gold then this is the shifter for you. Mile after mile AUDAX shifters will continue to serve you long after others have run out of juice or just plain frozen between gears. When simply better is better, AUDAX shifters are simply the best. STANDARD ROAD BRAKE PULL - compatible with traditional road road brakes - road calipers and cantilevers and road disc brakes and mini-v brakes.
