main purpose of this bottom bracket is to be able to take the day in and day
out wear and tear of both serious riders and quality product enthusiasts.

Premium Bearings for performance.
Carbonyte bearings are very high-performance, low rolling resistance
bearings, designed for speed. This means that they will not match
the endurance or longevity of (standard) ABEC-10 Extreme Application
Carbonyte bearings are extremely high-quality stainless steel cartridge
bearings, made to Phil Wood's exacting specifications and stringent
tolerance requirements. A proprietary Carbonyte grease is applied
to provide protection against wear, yet to allow for the low rolling
resistance you would expect from a race-day bearing. The seals are
not full-contact as would be found in standard bearings, which is how
contaminants enter the cartridge and can cause wear. For this
reason we do not recommend these bearings for year-round mountain bikers
or our round-the-world touring customers. This bearing is for racing or
fair weather riding.
The aluminum inner sleeve engages into the stainless cups supported with o-rings
for a secure fit and further protection from the elements, and the whole bottom
bracket unit is polished to the traditional Phil Wood
This bottom bracket is
serviceable and compatible with most crank manufacturers.
