TRUVATIV BOTTOM BRACKET - BMX AMERICAN-EURO ADAPTOR

Sram:

Truvativ BMX, American-Euro style bottom bracket adaptor. This bushing set allows you to mount a modern threaded cartridge bottom bracket unit, into a frame made for the old-style "Ashtabula" (one-piece) cranks. This saves you weight, improves shifting and allows the use of modern clipless pedals.
