Wiper Blade Set Bosch Aerotwin A977S

Description

Set of wipers Bosch Aerotwin A977S includes blades of 650 mm & 425 mm and boasts a frameless design.
Engineered for year-round use, the wiper blade set A977S maintains optimal contact and clear cleaning across both blades in any climate.

The Bosch A977S set of wipers offers an advanced asymmetric deflector, built to provide exceptional wipe quality in challenging environments.
An asymmetric spoiler is strategically positioned to channel airflow into optimal contact force while reducing aerodynamic resistance, applying extra pressure to the wind-facing edge so the blade hugs the glass during gusty conditions. The result is reduced lift and chatter even in demanding high-speed scenarios.
Tailored for windy climates, this spoiler enhances stability for dependable performance.

Frameless wiper blade offers a sleek beam profile, purpose-built to hold constant glass contact across complex windshield curves. A pre-curved spring-steel beam pairs with a premium silicone edge, ensuring a crystal-clear pass. Its wind-cheating contour cuts lift at highway speed, while tool-free quick-click mount suits most makes and models for hassle-free fitting. The frameless build shrugs off snow and ice, eliminates corrosion points, and hugs modern glass shapes for superior visibility. Drawbacks: higher upfront cost, refill inserts are non-serviceable, plastic adapters may embrittle in severe cold, and clamping force declines slightly on very flat windshields. Rinse with pH-neutral soap every three months and replace every 12–24 months (6–12 months in extreme climates). Experience silent clarity – upgrade now.

Windshield wipers in the Aerotwin family feature an advanced frameless construction and are supplied to the production lines of many leading vehicle makers.

Spring strips are produced from a special “Evodium” spring steel and maintain their original tension throughout the blade’s service life.
