SHIMANO ULTEGRA R8000 Crankset + Single Speed Chainring (Brand New Take-Off)
This SHIMANO ULTEGRA R8000 crankset is a brand new take-off, professionally removed from a prototype bike. The pedals have never been installed or ridden. Paired with a CNC-machined wide-narrow single-speed chainring and a genuine SHIMANO SM-BBR60 Ultegra bottom bracket, this setup delivers a premium drivetrain solution for fixed-gear and single-speed builds.
Featuring 170mm crankarms, the crankset is matched with a wide-narrow chainring to reduce the risk of chain drop during hard efforts. SHIMANO’s Hollowtech II design provides excellent stiffness, efficient power transfer, and proven long-term reliability.
The 46mm chainline provides extra clearance, making it ideal for single-speed conversions by keeping the chainring safely away from the chainstay while maintaining a clean, straight chainline.
