Description
Velocity And Longevity
Ceramic Speed Gravel bottom brackets are built with CeramicSpeed Coated bearings and equipped with UFO Long Life Grease for the ultimate in durability and protection in all environments.
The cups come with CeramicSpeed Bearings installed, coated bearings and hardened-steel races for longer life and less bearing drag.
CeramicSpeed Coated Bearings typically have frictional drag of 0.3-0.4 watts per set. That represents an average 75% drag reduction compared to standard bottom brackets. The hardened-steel races feature the CeramicSpeed Balls that are 100% smoother and 15% harder than the ceramic competition. The CeramicSpeed Bearings last at least three times longer than other bearings.
Coated Bearings drop friction further and increase lifespan. The coated races see a 50% drag reduction and an improvement in bearing life of 60%.

- Available in BB86 Shimano, PF30 SRAM, BSA Shimano and SRAM, and T47/86 Shimano and SRAM

Reviews
Got it on sale, was thirty something % off so compared to a usually very expensive upgrade and with extended lifetime as well as warranty; seemed a bit more reasonable and decided to spoil myself.
Construction seem high-end, haven't seen any hambini or comparable BBs in person so I'm not able to compare. Got the gravel version which is filled with long life grease; since I'm only riding in tarmac I replaced it with all round grease which seemed less thick and allowed more free rolling.
First kilometers riding, the BB sounded a bit loud, perhaps due to ceramic balls pressed against the races but then it went quieter and pedalling/rolling seemed easier.
Difference I could notice was it is now easier to beat inertia; far more noticeable when suddenly accelerating or increasing watts, if rolling at a chill constant pace I guess one would not be able to feel the difference.
Lifetime warranty is a plus, besides, bearings are serviceable compared to big 2 brands.
