CeramicSpeed BB30 Bottom Bracket for Shimano Road

CeramicSpeed BB30 Bottom Bracket for Shimano Road

The CeramicSpeed BB30 Bottom Bracket for Shimano Road standard opened up design possibilities for frames. Adapting it for Shimano cranks takes a special machined aluminum threaded bottom bracket that threads into itself.

CeramicSpeed bottom brackets are finished with CeramicSpeed Bearings. You have two choices in terms of bearings. The first choice is CeramicSpeed's low drag, long life standard bearing, with hardened-steel races and CeramicSpeed's super round CeramicSpeed Balls. The second choice is CeramicSpeed's coated bearing, which uses those same balls installed on coated, hardened-steel races for longer life and less bearing drag.

In The Box

• 1 bottom bracket with bearings installed.
• 2 dust covers installed.
• All Round Grease.
• Sticker sheet.

• Coated - CeramicSpeed's coated products are covered by a lifetime warranty. The unique coating formula is a metallic layer that covers the bearing races and makes them 75% harder than steel. Thanks to this, they are highly resistant to corrosion and the coating provides an even lower friction than our standard bearings. Even if the bearing is contaminated with degreaser, water or mud, the risk of bearing failure due to corrosion is negligible if you choose the coated version.

Technical Data

This CeramicSpeed BB30 Bottom Bracket for Shimano Road works with cranks that have 24mm thru-axle spindles.

Bottom brackets have several variables, but within that, CeramicSpeed standard Bearings typically have frictional drag of 0.3-0.4 watts per set. That’s in the range of a 75% drag reduction compared to standard bottom brackets. That’s thanks to 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 see another big bump in performance. The coated races see a 50% drag reduction and an improvement in bearing life of 60%.

Performance can be tuned by changing the grease. All Round Grease comes installed, but can be changed for lower drag Race Day Grease, or higher durability Long Life Grease, which adds a bit of drag but stays in when riding through messy conditions.
