Bearing Press Adapters
We offer a full line of bearing press adapters, also know as drifts, to fit all common bearing sizes found in today's bicycles. A drift is used in conjunction with a bearing press to align and push a bearing into a frame, suspension pivot, headset or bottom bracket cup. Using proper drift size allows the bearing to press in stright and true without damaging either the bearing or the component they are going into.
Designed to press in all current Wheels Mfg bottom brackets!
Our universal bottom bracket drift is designed to press all current Wheels Mfg bottom bracket cups in to your frame. The adapter is machined with multiple steps to fit common bottom bracket shell and bearing diameters listed in the Compatibility tab below. Each step is laser etched with the diameter size.
Drift can also can be used as a frame bottom bracket shell sizing guide!
- Inner hole sized to fit 1/2" threaded rod. Not for use with our PRESS-1 or PRESS-4
- Compatible with any other press with a 1/2" diameter rod
- Recommended for use with Wheels Mfg Universal BB Press.
- Machined aluminum
- Anodized Red
- Sold individually
We do not recommend it for use with our PRESS-1 or PRESS-4 handles, or any other press with a rod diameter less than 1/2". When used with a smaller rod, it is almost impossible to prevent the cups or bearings from pressing in straight.
Some bottom bracket installs may require two drifts. Read the Wheels Mfg Universal BB Press instructions to help determine how many drifts you need.
This 7-piece adapter set is used to install 22mm and larger inside diameter sealed bearings into bottom brackets. Includes adapters for the most common bottom bracket bearings for Shimano outboard cup BBs (HollowTech II), SRAM GXP, Truvativ, FSA, PF30 and BB30 bottom bracket bearings.
This set includes the following drifts and spacers:
- (2) - 6806 OB
- (2) - 2437 X 6805 OB
- (2) - 52X30 OB
- (1) - GXP-LEFT OB
Together they allow for easy installation of 10mm I.D. and larger bearings into hubs with shouldered axles, always pressing simultaneously on both the inner and outer race of the bearing and preventing damage during the installation process.
Adapters are designed to install the final bearing in hubs with shouldered axles. Includes adapters for 12 different size bearings ranging from 10mm to 20mm. All parts are laser etched for easy identification.
