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.
