This is YST sealed mechanism bottom bracket set for 1 piece cranks. Sealed mechanism is a bicycle industry term referring to a dust shield over the bearings (notice the black dust shields that keep dirt out that would normally make it past the cones on regular bottom bracket sets). This will fit most one piece cranks. It is threaded 24 threads per inch. This will NOT fit 28T threaded one piece cranks.
Color: BLACK
Included are:
* 2 cups
* 2 bearing retainers
* 2 lock cones
* 2 dust shields
* 1 lock washer
* 1 lock nut
* 1 chain ring space
Everything is new in the original box.
