Wood & Co. was founded in 1971 to produce maintenance-free hubs for
cyclists. At the time we manufactured the world's first production
sealed bearing bicycle hubs. As the demand for better products grew,
we developed components and items that enhanced the use of cycling
and wheelchair products."
".... The original production hub set consisted of a
basic front and rear hub. "
"We produced the
first sealed crank bearing cartridge system (circa
" Phil Wood & Co. produced the first
production sealed bearing pedal. It was the first pedal
to receive formal approval by the California Highway
Patrol. (Not currently in this years production)."

the man responsible for innovative sealed
hubs, bottom brackets and other bicycling products, died
this week on his farm in Baxter, Iowa. He was 84.
He started the Phil Wood Company in 1971 as primarily a
hub maker, though he offered other components. He sold
the business in 1991.
Peter Enright, the current president of the Phil Wood
Company remembers “He was complaining to Spence
Wolf (Famous proprietor of the Cupertino Bike Shop)
about why no one offered a sealed bearing hub and Wolf
told him to make his own hub. A little while later he
asked Spence how many he should make. It took Spence a
bit to remember what he was talking about. He said make
50 hubs and the business was launched.”

The Phil disc brake.
A Phil brake as
used on the front of a custom McLean (USA) racing tricycle
"The brake operates a lot like an
automobile clutch. A splined driver threads on to the hub. That in turn drives a splined
friction disc. The body on the brake is a backing plate and a pressure plate. The cable
actuating arms rotate cams that in turn cause four radially spaced lever arms to move the
pressure plate against friction disc and backing plate."
"The disc floats on the splined driver. There are 4
adjusting screws that move the pressure plate closer to the disc to allow for friction
disc wear. The brake assembly slides over the hub axle and is held in place by a rubber
"O" ring that seats in the groove in the hub axle. A reaction arm contacts the
frame and serves to function the same as the reaction arm on a coaster brake. The brake is
somewhat tricky to adjust but once mastered it functions well. The friction disc was made
from an asbestos material. Since the use of asbestos is no longer available the discs are
no longer available. A suitable replacement materials had been found, and along with the
high cost to manufacture it has since been discontinued."
