30 mm (BB30 & PF30)

Shockcraft has a number of bearing options available for BB30, PressFit 30, BBright & SI Bottom Brackets, including Monocrome stainless steel or chromium steel (ABEC3 or ABEC5), Enduro chromium steel (ABEC 5) and ceramic hybrid.

ABEC Grades

An ABEC code indicates the grade a bearing is made to.  Bearings with higher ABEC grade numbers have tighter manufacturing tolerances for running at higher speeds and a higher cost.  ABEC1 is the lowest grade, ABEC9 is the highest.

Monocrome Special 6 Months Guarantee

All MonocromeTM bearings carry a special guarantee with a 6 month no questions asked replacement.

Monocrome Screw-Fit 46 mm Bottom Bracket

Screw-Fit 46 mm Bottom BracketShockcraft also has its own aluminium hard shell Screw-Fit 46 mm unit for road and mountain frames with 46 mm ID BB30/PF30 bottom brackets.  Aluminium cups are much stiffer than plastic and prevent the bearings binding due to a tight frame fit, greatly improving bearing life.  They can also be machined down to fit frames which are out of tolerance.
