CeramicSpeed PF4130 MNT & MTB bottom bracket

This bottom bracket works with 30 mm thru-axle cranks. If you have a BB86 frame and want to install a 386EVO crank or Rotor 30mm crank, this is the right bottom bracket for you. 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. The grease can be changed as needed and as appropriate, for example, TT and Track Grease to reduce friction resistance or LongLife to increase durability. 

Included:

• 2 center caps
• 2 x 1 mm washers
• 2 x 0.5 mm washers
• 2 dust caps
• Rubber seal
• Plastic cage protector
• 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. Coated bearings have the same balls, but this bearing surface ensures longer durability and less friction between the bearings.
