Wheels Manufacturing 2437 Open Bore Adapter

This adapter is designed to help you press 24x37 sealed bearings into bottom bracket cups or direct-fit frames, such as Trek's BB90 system. It ensures the bearing is seated accurately without damaging the frame or the bearing itself.

It depends on your specific bottom bracket setup. While some installations can be done with one, many bearing press procedures require two drifts—one for each side—to ensure even pressure during the press.

The adapter features a 0.387-inch through-hole, which is designed to accommodate a standard 1/2-inch threaded rod. If your press uses a 1/2-inch rod, this adapter will be compatible.

This adapter is precision-machined for 24x37 sealed bearings. It is also specifically compatible with Wheels Manufacturing BP0006 and BP0007 bearing press systems.

Aluminum is chosen for its durability and lightweight nature, which helps it withstand the pressure of a bearing press without deforming. The red anodized finish provides a hard, protective layer that resists corrosion and makes the tool easy to identify in your toolbox.
