Smooth, durable performance with the RS500 Bottom Bracket for 68mm shells
What Our Gearhead® Experts Are Saying:
"I’ve used the RS500 on multiple 68mm road frames and it’s a breeze to install. The updated seal design really helps keep things clean, and the smooth spin is exactly what I want for long road days. It’s affordable, durable, and just works."
Whether we're cruising backroads or grinding out miles during the week, the Shimano RS500 Bottom Bracket gives us consistent, smooth pedaling every ride. Built specifically for 68mm BSA threaded bottom bracket shells, it pairs perfectly with Shimano's 24mm spindle cranksets for a tight, secure fit and dependable performance.
We trust Shimano’s updated seal design to keep grit and moisture out, reducing wear and extending the life of the bottom bracket. At just 92 grams, it's impressively light while staying tough enough to handle thousands of miles without a second thought.
