The Shimano RC500 Boa L6 Kit Left is a genuine replacement part designed specifically for Shimano RC5/RC500 road cycling shoes equipped with the Boa L6 closure system. Over time, dials and laces can wear out from regular use, crashes, or simple everyday abrasion. This left-side kit allows you to restore the precise micro-adjustability and secure fit you expect from your Boa-equipped Shimano shoes, without needing to replace the entire pair.
Ideal for riders who value performance and reliability, this kit helps keep your favorite road shoes in top condition, ensuring consistent tension and easy on-the-fly adjustments during training rides, races, or long endurance days. Using an original Shimano/Boa spare part means compatibility and function are maintained, so the dial turns smoothly and locks firmly as intended. It’s a smart, cost-effective way to extend the life of your footwear, maintain comfort, and preserve the responsive feel that makes Boa-equipped road shoes so popular among dedicated cyclists.
