Are the Promax B-3 Air Flow Pads Worth the Upgrade?

The Promax B-3 Air Flow brake pads are built around a co-molded one-piece construction that delivers long-term durability and consistent feel through thousands of braking cycles. The signature finned air flow design pulls heat away from the pad surface during extended braking, reducing fade on long descents where conventional pads start to feel soft and unpredictable. A dual-compound formulation optimizes friction across a range of temperatures, giving you reliable bite whether you're carving a cool morning descent or grinding through a sun-baked summer road ride.

At 70mm, these pads fit a wide range of rim brake calipers found on road, gravel, and commuter bikes. The pivoting post design simplifies installation and allows tool-free toe-in adjustment, so you can dial in pad angle for quieter, more progressive braking without pulling out a wrench. They're a straightforward upgrade for any rider who wants better heat management and longer pad life out of their rim brake setup.

FAQ

What brake systems do the Promax B-3 pads fit?

The B-3 pads measure 70mm and fit a wide range of standard rim brake calipers on road, gravel, and commuter bikes. Check your caliper specs to confirm compatibility before ordering.

How does the finned design help with braking performance?

The fins increase surface area exposed to airflow, dissipating heat more efficiently than a flat pad. This keeps the compound cooler during sustained braking and reduces fade on long descents.

How do I install and adjust the Promax B-3 brake pads?

The pivoting post design lets you set toe-in angle without tools. Slide the pad onto the pivot, position it against the rim, and tighten. Adjust the angle by hand until you get the alignment and sound you want.

Best For

Road, gravel, and commuter riders on rim brake bikes who want better heat management on long descents or hot-weather rides. Also a smart pick for anyone who frequently adjusts their pad toe-in and wants a setup they can tune without tools.
