It is said that the simplest ideas are always the best and this RSP Road Bike Chain Catcher is no exception. Constructed using a lightweight alloy (just 12gms) this device mounts to any band-on front mech. Here it sits quietly waiting for that frame scratching moment when the chain falls off and usually jams between the chainrings and BB shell taking several layers of paints with it. The small hook on the end of this device catchers the chain and allows for it to be re-fitted with ease without ever coming into contact with the frame. Ideal for carbon road bikes or those with sentimental value!
