クランク周りからパキパキと音がするようになって交換。元々付属していたのはSM-BB72-41Bからアップグレード。見事に異音も解消。この商品の回転が、、というのを見掛けるが、そもそもSHIMANOはBB以外も製品全体堅牢性や防水性が高いので設計思想が違うので何を求めるかですね。ちなみに元々完成車に付いてたBBはノーメンテで、雨の日も乗る場面があったが3年間問題なかったので耐久性は高かったのでさすがSHIMANO製だと思いました。

Siempre uso este eje pedalier con mis bielas Shimano Ultegra R6800 y R8000 y nunca he tenido un problema. La instalacion es facil con las herramientas adecuadas (prensa) y me suelen durar entre 15000 y 20000km.

My crank had some play, I had an event (Ironman Wales) coming and my bike required maintenance. These were easy to fit (with the right tools) and made the bike feel like new again, very happy.

This BB installed easy and function was good. Bearing quality and overall quality left a lot to be desired for a component wearing the Dura Ace label.

Perfect for the use on BB86. If you want to install at home. Parktool makes a 40 buck tool that will have the job done
