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.
