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 standard 43.5 mm chainline
- SKF JIS 110 mm for 45 mm chainline on bikes with widely-spaced chainstays
- Most other bottom brackets have slightly thinner spindles. We recommend JIS 110-113 mm bottom brackets.
Rene Herse crank bolts and pedal washers are included. Cranks are custom-assembled based on your order. Please allow 7-10 days until your order can ship.

IMPORTANT! Please don’t place an order with out-of-stock chainrings, even though our system allows this. (We’d have to cancel and refund your order minus 5-7% credit card/Paypal fees.) We apologize for the inconvenience.
