This is the new Shimano BB-UN300 square axle bottom bracket, which replaces older models - BB-UN26 and BB-UN55. This bottom bracket is suitable for a variety of bicycles: from city and touring to older road and mountain bikes.
Thanks to several different axle lengths and the BSA threading, the BB-UN300 is easy to match with most bicycles.
The bottom bracket connects the axle and the cranks through a square axle, ensuring a strong connection.
The set does not include crank fixing bolts.
