Rene Herse Double Crank
Where beauty meets performance. Rene Herse cranks are a modern classic. Thanks to their smart design and net-shape forging, they are among the lightest cranks available today, while offering a great choice of chainrings: from 52 to 24 teeth. Whether you want a classic racing double or ultra-compact cranks to match your pedaling style, Rene Herse cranks are available with the chainring combination you need.
Rene Herse cranks are designed for 5- to 9-speed systems. They are compatible with 10-speed systems when using a Shimano Ultegra chain, but we recommend our 9- to 12-speed cranks for optimum shifting performance with modern drivetrains.
Recommended bottom brackets:
- SKF JIS 107 mm for chainline on the big ring and ultra-narrow Q factor
- SKF JIS 110 mm for standard chainline
Rene Herse crank bolts and pedal washers are included. Choose your chainring combination:
