The Shimano 600 RD-6400 Rear Derailleur is a vintage component made in Japan, designed for 7-speed road and racing bikes. Constructed from durable aluminum alloy and steel, this short cage derailleur features a sleek silver color. With its compatibility specifically tailored for Shimano brand components, this rear derailleur is a reliable choice for cyclists looking to enhance their bike's performance with a touch of nostalgia from a classic design. This shows moderate wear due to it being in the ultrasonic cleaner too long.
