DG Great replacement for aging Ultegra 6700 BB. Really smooth rolling. Different tool needed for install.
Oscar So far (four days) I like it. It feels solid and smooth on the bike. It replaced a 105 bottom bracket.
Mr Osa 他社製品と比較すると滑らかさはやや劣りますが、精度が高いため、防水性に優れており安心してBB周りを洗車できます。レースよりもエンデュランスな使い方がお勧めかと思います。
Mick As expected and smooth. Nice finish to a Shimano setup
Mr N This BB is a low-cost and high-performance
SimoWill Good BB. Not sure if it's much better than the BBR60, but for the small difference in price, it's a no-brainer decision really. Merlin had the best price by far.
DEREK Great little bottom bracket, smooth and neat, but do not forget the special fitting tool !
Andy Great bottom bracket, super smooth and extremely well engineered, veryy smooth and easily fitted, and for the price you just cannot go wrong.
Jimmy Super light weight, easy installation and very rigid. I replaced classic crankset for dura-ace hollow tech surprisingly it made a huge difference on my vintage steel frame
Jack Like most high-end Shimano kit this bottom bracket is well engineered - and Merlin sells it at a very competitive price - it's a no-brainer really. Postage was cheap too...
Mr Madrid Very smooth ride and saving some weight, great quality
Mr Lefort Why would anyone buy any other shimano compatible BB? cheap as borscht and hyper reliable, spin like ceramic. Arrived in 5 days from UK to Canada.
