The SHIMANO OT-RS900 is a top - notch shift cable housing designed for rear derailleurs. With its excellent construction and high - quality materials, it guarantees a super smooth shifting experience for your bike's rear derailleur.

Using your Shimano OT - RS900 outer cable is easy. First, make sure your bike is on a stable stand. Carefully remove the old cable from the rear derailleur and replace it with the 240mm OT - RS900 cable. Make sure it's properly attached and adjusted. When it comes to maintenance, regularly check the cable for any signs of wear or damage. If you notice fraying or kinks, it's time to replace it. To keep it in good shape, you can clean it with a soft cloth every few rides. Also, avoid exposing it to extreme temperatures or harsh chemicals, as this can reduce its lifespan.
