CeramicSpeed BSA MNT Shimano bottom bracket 

This bottom bracket works with 24 mm thru-axle cranksets from Shimano, FSA, Rotor, and others. The friction coefficient of CeramicSpeed (CS) Standard bearings is typically 0.3-0.4 watts per bottom bracket. This reduces friction by 75% compared to standard bottom brackets. CS balls have 100% less friction and are 15% stronger than other ceramic balls on the market. The bearings last at least 3x longer than other standard bearings. MNT bearings come with All Around grease, MTBs come with LongLife grease. The grease can be changed as needed and as appropriate. Included:p>

• 2 threaded capsules
• 2 dust caps with spacer washers
• Spacer ring
• 10 mm All Round grease syringe
• Stickers

You can choose between two bearing surfaces. The standard bearing surface has a low friction coefficient thanks to the hardened bearing surface and ceramic bearing balls.nbsp;Coated bearings have the same balls, but this bearing surface ensures longer durability and less friction between the bearings.
