Rene Herse Tandem Triple Crank
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.
Rene Herse cranks are compatible with modern 10-speed drivetrains, as well as classic 5- to 9-speed systems. (See Technical Specs for details.)
Rene Herse crank bolts and pedal washers are included. The large choice of chainrings allow you to fine-tune your gearing to your riding style:
Outer Chainring (teeth)
52 50 48 46 44 42
Middle and Inner Rings (teeth)
44 42 38 36 34 33 32 30 28 26 24
Tandem Left-Side (teeth)
Crank length: Arm pair with triple chainrings is ‘drive arms’; the other set (right crank without chainring) are ‘connecting arms.’
We recommend SKF bottom brackets (JIS spindle) for Rene Herse cranks.
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.
