The ne plus ultra of sealed cartridge bottom brackets!
Consist of a cartridge and 2 mounting rings.
What makes
Phil Wood Bottom Brackets so great?
Phil cartridges can also be had with the same housings and titanium spindles. These are available upto 123 mm length by special order. They are approximately 60 gm lighter than the stainless ones above. Call us for pricing and availability info.
The Magnium - Titanium versions of Phil bottom brackets are also available by special order. The housing is Magnesium/Aluminum/Titanium and the spindle is titanium. They are available up to 130 mm in many of the same lengths as the Stainless Steel versions, but weigh approximately 130 gm less. Please call or email if you would like to discuss one of these.
Two Phil Mounting Rings are needed to hold the Bottom Bracket in the frame. Select your
frame's threading below.

E-Type derailers use BB Cups with an extended width drive side Phil Wood lockring. Call or e-mail us if you have an E-Type derailer.
So you will need a Phil Wood tool. Sold individually, but work better if used in pairs, especially on French/Italian threaded bottom brackets.

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.The B on the end of the Size Codes means Bolt. The spindle has threaded holes on each end to take bolts. Some older spindles had threaded ends that took nuts. Both styles work the same and hold the cranks on similarly, but the nutted spindles are a bit heavier.
Note that installing one of these spindles backwards will sometimes solve difficult chainline issues.
These are getting pretty scarce, we have run out of most sizes, and they are no longer in production. We do from time to time find NOS (New, Old Stock) parts so we might someday get new supplies of the discontinued sizes. Please do not contact us to ask about items marked "N/A".

- "3" series spindles normally fit 68 mm ISO/British/French bottom brackets
- "5" series spindles normally fit 70 mm Italian bottom brackets, also 68 mm French with thin cups
- "7" series 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.
