Brand new! Shimano - 122.5 mm - JIS - Square bottom bracket axle - Cr-Mo
The first bottom brackets, dating back to the early 20th century, used cotter pins. In the 1960s and 1970s, square JIS and ISO standards became the norm, offering robustness and ease of maintenance. The 1990s saw the arrival of sealed cartridge bearings, which are more durable and maintenance-free.
