Shimano CUES – Keeps You Moving

The highlight for all those who like to be active. Consistently developed for comfortable as well as safe movement and created with the aim of offering more versatility for the most diverse types of bikes. The experience-oriented CUES series combines incredibly smooth and stress-free shifting behavior with durability suitable for E-Bike use and up to three times greater longevity thanks to LinkGlide technology. With the U4030 components, Shimano is expanding the CUES family to offer riders another comfortable and at the same time low-maintenance option for use on road and gravel bikes.

Shimano CUES disc brake set consisting of the BL-U4030 lever and the hydraulic BR-U6030 brake caliper. Smooth and simple maintenance is ensured by the proven One Way Bleeding system and the Easy Hose Joint System which makes brake hose replacement considerably easier.

Shimano CUES Bl-U4030 brake lever

Noticeably more control for ambitious recreational athletes. The CUES brake lever for single-chainring drivetrain systems incorporates the advanced features of the 105 series. The results of intensive research into different hand shapes are reflected in an optimized design that includes a shorter reach and correspondingly improved positioning of the brake lever blade. Typical of Shimano, this is complemented by the reliable braking performance of hydraulic disc brakes – ideal for extended road and gravel rides.

Shimano CUES BR-U6030 brake caliper

The hydraulic Flatmount brake caliper of the Shimano CUES series was specifically developed for a brake disc diameter of 160 mm. This is accompanied by an integrated design that makes an additional adapter superfluous. With its slim and lightweight 2-piston construction, the BR-U6030 brake caliper ensures reliable braking performance in all conditions.

J-Kit (Easy Hose Joint System) | For brake systems with J-Kit brake hose connection, the brake lever has an integrated squeeze seal (olive), which makes the installation and removal of the brake line much easier overall.
