Promax BL-47 Dual

Symmetrical Control. Single-Handed Safety.

The Promax BL-47 is a high-quality, forged aluminum lever designed to pull two brake cables simultaneously. Unlike "jumper" cables or flimsy adapters, the BL-47 features a dedicated dual-cable housing stop and a reinforced pivot point to ensure that the braking force is distributed evenly. This provides a firm, predictable feel that allows you to manage your speed with total confidence using just one hand.

Why the BL-47 is the Smart Choice for Specialized Builds:

• Dual-Cable Pull System: The internal cradle is designed to seat two cable heads side-by-side, pulling both equally. This is ideal for riders who prefer to keep one hand free for signals or gear shifts.

• Forged Aluminum Construction: Not all levers are created equal; the BL-47 is forged, not cast, offering superior strength and resistance to snapping under emergency braking loads.

• Four-Finger Ergonomics: The "long-reach" lever blade provides massive leverage, making it easy to generate high stopping power even when pulling the resistance of two separate brake calipers.

• Independent Barrel Adjusters: Features two high-precision barrel adjusters, allowing you to fine-tune the tension of the front and rear brakes independently to ensure your pads hit the rims or discs at exactly the same time.

• Integrated Reach Adjust: Includes a dedicated reach-adjustment screw, making it easy to customize the lever distance for riders with smaller hands or those wearing thick winter gloves.

• Universal 22.2mm Clamp: Designed to fit all standard flat, riser, and cruiser handlebars, making it a "plug-and-play" upgrade for almost any bike.

The Alegro Perspective: We call the BL-47 the "Problem Solver." It is a lifesaver for adaptive cycling builds or for riders building "safety-first" bikes. The dual-pull action is remarkably smooth, and because it’s made by Promax, you know the tolerances are tight. Pro tip: When setting this up, we recommend using fresh cables. Since you're pulling twice the load, minimizing friction is the key to getting that snappy, professional lever feel.
