SHIMANO DURA-ACE BB-7410 BSA
The 7400 series Dura-Ace group saw several interations including the introduction of 6 then 7 and finally 8 speed SIS shifting.
It was developed to give the professional racing cyclist a fraction-of-a-second advantage that can spell the difference between victory and defeat.
In near mint condition this bottom bracket is the perfect finishing piece for your high end Japanese build.
