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 and aerospace grade titanium. Standard spindle lengths range from 102mm to well over 155mm. Cartridge widths are available for bottom bracket shells in 63, 68, 73, or 100mm with any spindle length to accommodate the target frame. Custom spindle lengths and cartridge widths are available upon special request.
Bottom brackets will not work without cups, and must be installed with Phil Wood specific tools.
