Rene Herse Single Speed/Fixed Gear Crank
$455.00
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 42 teeth.
Rene Herse crank bolts and pedal washers are included. Free choice of chainrings (teeth):
52 50 48 46 44 42
Important: The single-speed/fixed cranks use standard Rene Herse chainrings. They are intended for fixed-gear and single-speed setups with straight chainlines. For One-By drivetrains, use our Rene Herse One-By cranks.
We recommend SKF JIS 107 mm bottom brackets for Rene Herse single cranks.
