dura ace track 10
true or false: dura ace pitch gruppo bottom brackets were never introduced with italian threading.
correct me if im wrong.
The bottom bracket it came with was a standard square-taper bottom bracket with standard track dimensions so you could actually use any threading you wanted. I've seen enough 10-pitch gruppos on Colnagos and other Italian track frames. I purchased a couple 10-pitch gruppos when they were new and I do believe that the complete group only came with English threading, although a dealer could swap out the bottom bracket as needed.
