T47 Bottom Brackets | Full Engineering Guide | Everything you need to know

A lot of new bikes are coming out with T47 bottom brackets, this video explains what they are and how they work. In my opinion, this is a step in the wrong direction. The addition of an additional threaded connection makes it less stiff and introduces another tolerance and alignment stack. This is an admission by the bike industry that they are unable to make something to the required tolerances. T47 will generally have a higher system weight and a bonded joint that is liable to galvanic attack. More info on the technical standard https://www.hambini.com/engineering-g...
