Wheels Manufacturing 386 EVO Bottom Bracket Adapter

Yes, this adapter is specifically designed to bridge the gap between 386EVO bottom bracket shells and standard 24mm spindle cranksets, including Shimano Hollowtech-II models.

Because these are press-fit shims, you will need a bearing press tool to seat them properly into your existing 6806 bearings. Avoid using a hammer or improvised tools, as this can damage the precision-machined aluminum.

While it is optimized for Shimano Hollowtech-II, it will work with any crankset that utilizes a true 24mm spindle diameter. Just ensure your specific crankset does not have proprietary spindle length requirements that differ from the 386EVO shell width.

No, this adapter is designed to press directly into the 6806 bearings already installed in your 386EVO bottom bracket shell. It essentially acts as a reducer sleeve to accommodate the smaller 24mm spindle.

When installed correctly into a properly faced bottom bracket shell, this adapter provides a very secure, stable interface. If you experience creaking, it is usually a sign that the bearings themselves need service or that the adapter requires a light application of high-quality grease during installation.
