Finally a 12- and 11-speed-compatible crank that rivals the very best from the big makers in shifting performance, offers chainring combinations useful for most riders, and the beauty and polish of our Rene Herse cranks. The cranks are designed to be 100% compatible with STI (except 12-speed mtb), Ergopower (all versions) and SRAM (all versions). They work equally well with 9- and 10-speed drivetrains, and also with downtube or bar-end shifters.

The completely new outer chainrings were designed to work with the inner rings as a dynamic system to offer an optimized chain path at 50-130 rpm (and not statically, as with many other chainrings). This ensures smooth and quick shifts even with the steep chain path inherent in the narrow spacing of 12/11-speed chainrings. When using with 10- or 11-speed, we recommend Shimano Ultegra 11-speed chains – even if you run derailleurs and cassettes from other brands, use a Shimano Ultegra 11-speed chain. Existing Rene Herse cranks can be retrofitted to 12- or 11-speed by swapping out the big chainring.

Rene Herse crank bolts and pedal washers are included.
