Square Taper Bottom Brackets
Phil Wood & Co. manufactures square taper bottom brackets for nearly all square taper cranks. The spindles are made out of either US produced heat-treated stainless steel or aerospace grade titanium. Spindle lengths range from 102 mm to 185 mm. The spindles are sold as either a plain spindle (for use with press-fit style bottom bracket shells) or assembled in a cartridge with bearings. Cartridge widths are available for bottom bracket shells in 63, 68, 73, or 100 mm with any spindle length to accommodate the target frame. Custom spindle lengths and cartridge widths are available upon special request.
Our cups (also known as mounting rings) are sold separately from the bottom brackets and are available in all the threading (British, Italian, Raleigh Super Corsa, French, Swiss, and Chater Lea). Extended cups with a left-hand lock ring are available in British threading for use with E-Type derailleurs or to hold a bracket to mount a chain guard. Occasionally, when British threads are damaged, mechanics have been known to salvage the frame by tapping the damaged side for Italian threading and installing an Italian cup on that side. Phil Wood cups are also available in singles to accommodate these issues.
Please Note: In order to install our square taper bottom bracket cups you will need either our Portable Phil Wood Square Taper Bottom Bracket Installation Tool or Professional Shop Phil Square Taper Bottom Bracket Installation Tool.
