The new René Herse cranks have entered production. The arms are being forged, the chainrings are being machined, and the crank bolts are being made, each by specialist manufacturers who are among the best in their trade. The photo above shows the final production version of the arms and chainrings. (The crank bolt still is a prototype.)
We plan to have the cranks in stock for the Holidays. We also have finalized the prices: £275.00 for single- and double-chainring cranksets, and £295.00 for a triple. We will offer tandem cranksets as well.
The double-chainring cranks are designed for a 113 mm JIS bottom bracket, resulting in a tread (Q factor) of 142 mm with a standard chainline. (If you ride mostly on the big ring, you can use a shorter BB spindle to move the cranks inward a bit, if your frame permits. This will reduce the tread/Q factor by up to 6 mm.)
The new René Herse cranks are compatible with many bottom brackets, including the excellent SKF bottom bracket available from Shedborn Bikes.
