The Shimano SM-BB94-41A Pressfit bottom bracket is used to install 24 mm Hollowtech II cranks from the XTR series in MTB bottom brackets with a width of 89 or 92 mm and a diameter of 41 mm. Thanks to the small ball bearings, it is almost 20 grams lighter than its predecessor. The smooth running and the durable seals are also convincing.
