Sealed Cartridge Bottom Brackets
Made In USA!
Consist of a cartridge and 2 mounting rings.
What makes Phil Wood Bottom Brackets so great?
- 17 mm Proprietary Heat-Treated Stainless
Steel spindle for maximum durability & minimum flex
- Provided
with sealed cartridge bearings in models for both 68 and 73 mm BB shells
- Unique cupped flats for crank
arm retention with a shell designed to seal out contamination from inside the frame.
- Wide bearing separation provides maximum spindle rigidity with cups providing 5
mm of added adjustment
- A bazillion different lengths and offsets to match virtually any frame and crankset combination.
Plus the ability to shift the bottom bracket left or right by up to 5 mm, allowing optimum chainlines.
- Basic Phil Wood information
- All cartridges are compatible with all cups and tools.
- All Phil Wood BB cups require use of the Phil Wood BB cup installation tool.
- The British and Italian anodized alloy cups are compatible with aluminum and titanium BB shells.
- 68 mm Cartridges will have approximately 2.5 mm of the rings extending from both sides of a 68 mm shell.
The 68 mm cartridge in a 73 mm shell will allow the rings to be flush with the shell.
- Phil Wood cups should be installed with supplied thread locking compound or Blue Loctite 242
when used in steel, aluminum, and titanium bottom bracket shells

New! Phil BB Mudguards
Designed to help protect your Phil Wood bottom bracket cups from getting dust, dirt and mud that can accumulate in and around the bottom bracket cup splines. They have a drain opening to allow any moisture between the bearings and mudguard to vent out.They are made to install onto any Phil Wood square taper bottom bracket cup sets.
Each set of mud guards comes with 4 rubber o-rings, (preinstalled and two replacement).
Available in Black or Silver:
BB235 Silver Mudguard Set $18.95
BB236 Black Mudguard Set $24.95
Tools for Phil Wood Bottom Brackets
The diameter and notch pattern on the Phil Wood mounting rings are not the same as any other BB mounting system. (That's not because they choose to be different...Phil was the first to use this type of mounting, other makers of cartrdige bbs chose to create their own proprietary tooling.)
So you will need
a Phil Wood tool. Sold individually, but work better if used in pairs, especially on French/Italian threaded bottom brackets.

Old-style Cup-and-Cone Bottom Bracket Parts
Cartridge bottom brackets are really superior technology, but for some older bikes, suitable cartridge bottom brackets may not be available.
We stock the necessary parts for many older bicycles.
We are currently not offering these spindles. We've had too many quality control issues with them.
|---|
- "3" series spindles normally fit 68 mm ISO/British/French bottom brackets
- "5" series (N/A) spindles normally fit 70 mm Italian bottom brackets, also 68 mm French with thin cups
- "7" series (N/A) spindles fit "oversized" 73 mm ISO/British bottom brackets, sometimes also work with Raleigh 26 tpi cups in older Nottingham-built Raleigh bikes.
- Models designated "-B" use bolts, others use nuts. Length measurement does not include the protruding thread for nut-type spindles.

Grade 25 1/4" Balls bag of 25
Virtually all traditional bottom brackets use 11 1/4" balls on each side. These are the highest quality, grade 25. Many shops use the cheaper grade 100 or even grade 300, but we feel that at this price anybody can afford the best.
Using indivual loose balls is gives better results than balls in retainers, so we don't carry retainers for this application. The primary advantage of using retainers is slightly faster assembly at the factory, and also the opportunity to use fewer balls.
The 1/4" size also fits most rear hubs, 9 per side, so you might want to stock up.

Don't forget to use plenty of grease!
Sleeves $1.95
These accordion-style sleeves will greatly extend the life of your
bottom bracket by preventing crud from inside the frame from reaching the bearings.
