Hawk Pressfit 30

The Pressfit 30 bottom bracket is designed to fit PF30 frames and it has been redesigned without the sleeve attached to one cup; reducing the weight by 18g. Installed are Folmer TechnologyTM bearings that support 30mm crank sets such as SRAM, RaceFace, and FSA.

There are 3 different bearing choices to best meet your needs:

• Standard Bearings: Use for road bikes in dry/no salt environments.
• Full Stainless Steel Bearings: Use for extreme distance riding (>200miles/week), BMX, MTN, Cycle cross, and other varying conditions.
• Full Stainless Steel Bearings with CX Seals: The CX seal is for riding conditions where water, dust, and debris can get into the bearing and degrade it prematurely. Use for MTN, BMX, Cycle Cross, or other wet and dirty conditions. NOTE: This is not for timed road biking as the extra seal slightly increases wattage.

The BB.PF30 has an optional middle tube (Di2) to be used with electronic shifters, such as the Shimano Di2, ensuring the cables do not rub on the crank spindle. The middle tube is available in 41mm (road), 46mm (mtn), and 52mm (Cervelo) and is sold separately.
