The Italian SHIMANO Ultegra 6800 bottom bracket features new bearings with a 50% lower friction rate than the 6700 model.
The result is increased durability and smoothness. It features a screw thread for mounting on frames with Italian screw thread, and is compatible with SHIMANO cranksets featuring Hollowtech II construction.

"Fast. Returned old one with no problem (ordering error on my part)"
"I bought this product to renovate a 90's mountain bike with an Italian thread. Easy to assemble, but the tightening is still tricky to grasp as the plastic tool disintegrates as you go along... ... . In short, once assembled (be careful, you have to tighten it all the way) everything's perfect."
"Perfect; mounted on my colnago master to mdernize it with a shimano ultegra 6800 crankset; perfect"
"product mounted on an italian bike no problem for the assembly the wrench with the right diameter for the assembly is provided".
"I bought this bottom bracket set so I could mount an XT crankset on an Italian frame. No worries."
"After making a mistake with my order, I sent back the first box, which was reimbursed, and bought this one, which works perfectly."
"Bought a week ago Easy assembly but not a solid tool at all".
"Product absolutely conforms to the explanation provided. Tools included adequate."
"I am disappointed by the plastic wrench it did not resist when tightened as well as the spacers do not fit too small diameter otherwise everything is fine!!!"
