An ideal choice for anyone replacing a worn bottom bracket on an ITA-threaded frame fitted with Shimano HOLLOWTECH II cranks.
The Shimano Ultegra SM-BBR60 is a threaded bottom bracket for frames with a 70 mm Italian-threaded shell. It is designed for HOLLOWTECH II crank systems, with the bearings positioned outboard to support efficient power transfer and smooth crank rotation.
For day-to-day riding, the appeal is straightforward: a proven replacement that keeps the drivetrain turning freely without unnecessary complexity. The sealed bearing area helps guard against dirt and moisture, while the compact bearing design keeps weight to a claimed 100 g.
Choose the SM-BBR60 when you need a dependable Shimano bottom bracket for an ITA-threaded road or performance bike. Take care with fit before ordering: this model is for ITA threading and 70 mm shells, not every threaded frame standard. Installation may also require the appropriate Shimano HOLLOWTECH II bottom-bracket tool; a supplied plastic adapter can allow use with older compatible tools.
