Krankboks CeramicSpeed PF4630
Krankboks CeramicSpeed PF4630
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.
This bottom bracket features nearly zero loss of power due to friction, thanks to the bearings. Either our Standard or Coated Bearings. Both have super round, super smooth CeramicSpeed balls rolling on hardened-steel races. The Coated version has 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.
In The Box:
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. Standard Bearings typically have frictional drag of 0.3-0.4 watts per set. That’s in the range of a 75% drag reduction versus conventional bb’s. The bearings last at least 3x longer than other bearings.
Change the grease for your rides. TT and Track, All Round, and LongLife are greases CS designed. The first is the least drag, the last is the most durable. All Round, in the middle, comes in road bearings.
CeramicSpeed Bottom Brackets:
The CeramicSpeed Bottom Brackets guarantee you the lowest friction, optimised power transfer, and longest product lifetime, helping you to save watts or ride faster. Fitting almost all standards available on the market, more than 150 types of CeramicSpeed Bottom Brackets are available for upgrading your bike.

No matter the discipline, there's a CeramicSpeed Bottom Bracket that fits. The Bottom Brackets come in both road, tri and MTB specific variants.

Coated Bottom Brackets for even better performance:
All of the CeramicSpeed Bottom Brackets come in a coated version for even longer lifetime and lower friction. The coating on the Bottom Brackets is a thin metallic layer that is 75% harder than the hardened-steel races and which offers an even better performance than the non-coated CeramicSpeed Bottom Brackets.
