Wheels Manufacturing PF30A Bottom Bracket

This model is specifically designed for frames with a PF30A or Specialized Carbon OSBB interface. It fits shell widths between 61mm and 73mm, so verify your frame's specific shell width before purchasing.

Yes, this bottom bracket is engineered specifically for SRAM DUB cranksets with a 29mm spindle diameter. It ensures a precise fit and smooth rotation for that specific standard.

Unlike standard press-fit bearings that rely on friction alone, this design features two cups that thread into each other. This locks the assembly firmly into the frame, which significantly reduces the likelihood of creaking and improves overall stability.

Yes, you will need a bottom bracket tool compatible with a 48.5mm, 16-notch interface to tighten the cups. Because the cups thread together, you will need two of these tools—one for each side—to properly secure the assembly.

Yes, the unit uses high-quality Enduro ABEC-3 bearings. Because the cups are machined aluminum and threaded, you can service or replace the bearings down the road without needing to replace the entire bottom bracket assembly.

The primary advantage is reliability. By threading the cups together, you eliminate the micro-movements that typically cause press-fit bottom brackets to creak over time, providing a much quieter and more durable ride.
