Rene Herse Tandem Double Crank

$770.00$800.00

Rene Herse tandem cranks are made to the same ultra-high specifications as our single-bike cranks. 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 with standard rings are compatible with 5- to 9-speed systems. For 9/10/11-speed drivetrains, choose our ramped-and-pinned 11-speed chainrings.

Rene Herse crank bolts and pedal washers are included. Choose your chainring combination:
