Colnago framesets such as the C64 and V2-R that use the ThreadFit 82.5 bottom bracket interface require a set of threaded shells that accept PressFit BB86 type bottom bracket bearings. New frames will come with these precision machined shells, but if you need to replace yours, or simply outfit a frame, this pair is the part you require. Colnago developed this system because they believed it more precise than machining a carbon frame to directly match a bearing system. Many of you have ridden on or with with bikes that seem to creak from the bottom bracket no matter is done to stop it, and this will appreciate this attention to detail.

By offering precision shells for bearings to pressed into, Colnago controls the interface. And because it is possible over time for these aluminum shells to wear from bearing interaction, they are easy to replace. The external 16-notch spline design is very low profile, so Colnago also sells a perfectly matched tool that won't mar your frame when you install the shells. Each shell is side-specific and is clearly marked with drive or non-drive indicators, as well as an directional arrow for proper threading. The threads come with thread locking compound already installed and we encourage you to use grease as well.
