The Shimano RP400+W Boa L6 Kit White Left is a genuine replacement part designed specifically for Shimano RP4 series women’s road shoes equipped with the Boa L6 closure system. Over time, dials and lace systems can wear out or become damaged, and this left-side kit allows you to restore the precise fit and easy adjustability you expect from your shoes without needing to replace the entire pair. Using an original Shimano and Boa component helps ensure smooth operation, reliable retention, and compatibility with the existing mounting points on your shoe.
This kit is ideal for riders who value a secure, micro-adjustable fit for long road rides, training sessions, or indoor cycling. The Boa L6 dial is known for its simple twist-to-tighten, pull-to-release functionality, making on-the-fly adjustments quick and intuitive, even with gloves. The clean white finish matches the original aesthetic of your RP400W shoes, keeping your footwear looking sharp while performing like new. Whether you are refreshing a well-loved pair or repairing accidental damage, this left-side Boa L6 kit is a practical, cost-effective way to extend the life of your Shimano road shoes.
