Wiper Blade Set Bosch Aerotwin RLE A721S

Description

The Bosch Aerotwin RLE A721S comes as a frameless construction wiper blade set with 600 / 400 mm blades.
The set of wipers Bosch Aerotwin RLE A721S offers uninterrupted, all-weather performance for both blades in rain, snowstorms, and high-temperature heat.

The Bosch Aerotwin RLE A721S set of wiper blades integrates an asymmetric-style spoiler, optimized for unmatched clarity in all conditions.
An asymmetric spoiler is strategically positioned to channel airflow into enhanced blade pressure 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 strong crosswinds.
Tailored for windy climates, it enhances stability for lasting clarity.

Frameless windshield wiper blade unleashes a modern tensioned beam, precision-engineered to maintain constant glass contact across today’s sculpted windshields. A pre-curved spring-steel beam pairs with a premium silicone edge, ensuring a whisper-quiet glide. Its low-drag aero spoiler boosts high-speed stability, while slide-in multi-adapter suits 95% of vehicles 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.
