BOX EXTREMUM BB
The Extremum RacePrep™ is first external BB designed for BMX racing and features non-
contact, titanium-coated SUS bearings, modified low-friction seals and lighter weight lube. The
titanium coating results in a low friction coefficient, increased corrosion resistance and smoother
rolling bearings. The result is a BB with less drag and a level of bearing protection more in line
with the needs of BMX racers.
PROMAX EX-1 BB
EX-1 External bottom brackets feature cold-forged and CNC-
machined alloy cups, dual-labyrinth bearing covers and precision
sealed bearings. They are the perfect match to Promax CF-2 and
HF-2 cranks and ultimate upgrade to the budget BBs sold with
most crank sets.
