SM-BB71-41C is the Shimano Pressfit bottom bracket, which is best suited for Saint and ZEE cranks, because it is compatible with bottom bracket housings from 104 to 107 mm. Of course, this bottom bracket also has 24 mm bearings and axle diameters, as are common for Hollowtech II. This ensures the best combination of rigidity, tightness and weight.
