Jan Heine(of Compass Bicycle and Bicycle Quarterly)is introducing a reproduction Rene Herse crank. Well, maybe not a reproduction, it might be better to say he is putting them back into production. They can be purchased as either a single, double, or triple chain ring setup. Only one crank arm length, 171mm, and chainring sizes are from 24 to 48 tooth, in 2 tooth increments. For $400, that is a great looking crank, and I will be getting one for my Hanford.
