CeramicSpeed PF4630 30mm Gravel CX Coated Bottom Bracket (Black)

PF4630 Bottom Bracket Gravel

This bottom bracket is when you have a PF30, BBright, or 386EVO shell frame and want to install a BB30 crankset into the frame. All have a 46mm inner diameter and smooth insides, though the widths vary from 68mm to 86mm. The crank has a 30mm diameter spindle.

Onze Gravel bottom brackets zijn gebouwd met CeramicSpeed gecoate lagers en voorzien van UFO Long Life Grease voor de ultieme duurzaamheid en bescherming in alle omgevingen.

This bottom bracket features nearly zero loss of power due to friction, thanks to the bearings. The bottom bracket has super round, super smooth CeramicSpeed balls rolling on hardened-steel races. With a metallic coating laid onto the races, making them even harder and smoother, resulting in longer life and lower drag. They come installed in cups.

Technische gegevens

30mm thru-axle cranks are increasingly popular due to high stiffness and low weight. 46mm inner diameter bottom brackets are popular for the freedom they offer designer in building frames. Because of the variety of widths, the cups here extend into the shell and come with a telescoping spacer tube to further seal and stiffen the system.

The bottom bracket is already stiff thanks to hard ceramic bearings and hardened-steel races. Thanks to CeramicSpeed, it’s also nearly zero drag.
