Wheels Manufacturing 386 EVO Bottom Bracket Adapter

No, this specific adapter is designed exclusively for 24mm non-tapered spindles, such as Shimano Hollowtech-II. It will not fit SRAM GXP cranks, which use a stepped 24/22mm spindle.

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

Yes, these adapters are designed to be durable and can be removed and reinstalled if you decide to change your crankset. However, ensure you clean and lightly grease the surfaces before re-pressing them to prevent creaking.

Creaking is often a result of improper installation or lack of lubrication. When installing these, apply a high-quality bicycle grease to the contact surfaces to ensure a silent, secure fit.
