The SRAM Staubscheibe/Wellenscheibe BB30 is a small but essential component for riders who want a smooth-running and long-lasting bottom bracket. Designed specifically for BB30 crank and bottom bracket systems, this dust and wave washer combination helps to keep contaminants away from the bearings while maintaining the correct preload on the crank spindle. By compensating for minor tolerances in the frame and bottom bracket assembly, the wave washer ensures that your crankset spins freely without unwanted play or binding.
Ideal for both maintenance and replacement, this SRAM BB30 dust and wave washer set is a smart addition to any home workshop or professional service kit. It is typically used when installing or servicing BB30 cranksets on road, MTB, or gravel bikes that use this standard. With proper use, it can help extend bearing life, reduce creaks, and improve overall drivetrain performance. Whether you are refreshing a worn bottom bracket or building up a new frame, this small part plays a big role in keeping your bike running quietly and efficiently.
