Screw thread type

Thierry

Hello, What is the type of thread for this bottom bracket and what is the difference with the "Shimano UN-300 BSA Bottom Bracket Axle"? THANKS

Answer of Andrea

it is BSA, the right main cap screws on counterclockwise and the left one clockwise. I got it for my MTB, and I´m happy with it, no problems. I don´t know the differences with the other movement in terms of product construction, perhaps just the pin width measurements, nothing else. They are both SHIMANO, the quality I imagine is the same. Pay attention to the size needed for your 68/73 bike, and the axle width needed for your crankset and transmission.
