Cyclists, these little silicone cable protectors are a simple upgrade that makes a big difference in your bike's performance and appearance! The RC125 upgrade version features a buffer design with soft silicone gel that reduces sloshing and drag resistance in your brake cables. The fluorescent green color adds a cool custom touch that makes your bike stand out. Each protector is about 10mm (0.39 inches) long and slides easily onto your inner brake cables. They help prevent cable rattle, reduce friction for smoother braking, and protect your frame from cable rub marks. Installation is super simple - just slide them onto your existing cables where they enter stops or guides. You get 10 protectors in the pack, which is enough for multiple bikes or to have spares. The silicone material is flexible and durable, standing up to weather and UV exposure. Whether you're building up a new bike, maintaining your current ride, or just want to eliminate that annoying cable noise, these little protectors deliver big results for a small investment. Your bike will look cleaner and operate smoother with these installed!
