More Info

Phil Wood offers square taper bottom brackets in JIS, JIS low profile, and Campagnolo/ISO tapers. We offer all three tapers to try and best meet the needs of customers who are using square-tapered bottom brackets. An explanation of the different bottom bracket tapers can be found here. In brief, most modern cranks will take the JIS (Japanese Industrial Standard) taper, in addition to Campagnolo cranks produced before 1994. After 1994, Campagnolo moved to the ISO (a.k.a. Campy) taper. The least common of the three tapers offered is the JIS low profile, which is used in some specific older-model Dura Ace cranks. (Phil Wood does not make bottom brackets that are compatible with ISIS or cottered crank systems.)

Our bottom brackets and threaded cups are sold separately, allowing the end user to mix-and-match to create the correct taper, spindle length, and threading combination. The design of our cups allows for an additional 5 mm of lateral chainline adjustment.

- Available in British and Italian thread
