Wiper Blade Set Bosch Aerotwin RLE A639S

Description

The Bosch Aerotwin RLE A639S comes as a frameless construction set of wipers with 650 / 530 mm blades.
Engineered for all-weather performance, the wiper blade set A639S ensures crystal-clear cleaning across both blades in any climate.

This Bosch A639S set of wipers features an advanced asymmetric deflector, optimized for unmatched clarity in challenging environments.
An asymmetric spoiler is strategically positioned to channel airflow into targeted downforce while minimizing drag, applying extra pressure to the wind-facing edge so the blade hugs the glass during fast-paced drives. The result is reduced lift and chatter even in turbulent weather.
Perfect for performance-driven drivers, this spoiler enhances stability for lasting clarity.

Frameless replacement blade unleashes a sleek beam profile, purpose-built to hold constant glass contact across complex windshield curves. A pre-curved spring-steel beam pairs with a advanced synthetic-rubber 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 rapid installation. 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). Go beam, drive clear – shop today.
