Shimano Ultegra 6800 BBR-60 Bottom Bracket

About Shimano Ultegra 6800 BBR-60 Bottom Bracket

Shimano have produced a new BBR-60 bottom bracket to compliment the new Ultegra 6800 11 speed groupset. In line with the rest of the gropset this bottom bracket is both lighter and more efficient than it's predecessor. It's15g lighter than the Ultegra 6700 bottom bracket at 76g,and Shimano claim a 50% reduction in rotational friction thanks to trickle down seal technology from the Dura Ace 9000 series.

As well as being the perfect match for the Ultegra 6800 crankset the BBR-60 is also backward compatible with any Shimano Hollowtech II crankset. A smooth upgrade for a slick price!
