Shimano Hollowtech II bottom bracket assembly. The minimal bearing interface gives super smooth rotation and reduced weight while the sealed cups effectively keep out dirt and water for maintenance free performance ride after ride.
Cheap and cheerful BB. I’m lucky if they last me a year, but they are a doddle to install and reasonable quality. Delivered quickly by Vanilla

Hollow tech BB
Nice and easy to use. Non drive side had become dry and not smooth. So maybe a seal issue with the design. Make sure you have the socket tool for installation as this works well with a rachet and gives good leverage.
