Pre-Orders for René Herse Cranks

Pre-Orders for René Herse Cranks

Developing an excellent product takes time and care. The first run of our new René Herse cranks has been forged. Above, you see a raw forging being removed from the forging die.

Above are the raw forgings for the crankarms of the first production run (three containers in the foreground). Around the same time, the forge was making suspension linkages for 2013 model year mountain bikes (talk about a long lead-time!).

Now our chainring tabs, square tapers and pedal eyes have to be machined (above). The first batch of 50 cranksets is being machined right now, from which we will check all the tolerances to make sure the tapers are accurate and the chainrings have the absolute minimum runout possible. Once we have ensured that everything meets our high standards, the full production run will be machined.

Our engineer in Taiwan (above on the left) visits the forging and CNC shops every week to make sure everything is to spec.
The first 50 sets of cranks should arrive here in late December or early January, together with the 48-tooth and 32-tooth chainrings. Other chainring sizes, more cranks (including single-chainring and tandem models) will follow shortly thereafter.

We are now taking pre-orders for the René Herse cranks, which will be filled “first come, first served.” Obviously, if you order a 48-32 double, you’ll get yours from the very first shipment, whereas other sizes will take a little longer (but not much). Tandem cranks and triples for half-step gearing probably will come last. Click here for more information.
At this time, we also would like to announce that Compass Bicycles is the sole manufacturer of René Herse cranks.  Herse Bicycles Inc. of Boulder, CO, has decided to focus on their core competencies of making superb custom-made bicycles under the René Herse brand. The René Herse cranks will be available directly from Compass Bicycles. The cranks also will be available from bicycle retailers.

    That must be extremely exciting to be getting this close. I hope Santa gives me some spending money.

    Already purchased, but your cart doesn’t work properly. When purchasing a double it still lists a third ring.

    I’ve been waiting for this notice. Will you accept orders from outside the US?
    What is the smallest size of chainring with triple circle design (used as outer), and largest one with single circle design (inner)?
    I want to order triple but I prefer triple circle chainring on both outer and center.
    In adition, I can’t find 40 teeth ring. Is it available?
    Thanks, Hiro

    Hi Jan,
    Does this crank work only on 10 speeds or can the crank be used with any number of rear gears?
    Thank you for all the hard work ( even if this a labor of love, the research and publishing take time away from your family) you do to educate all of us of lost bicycling knowledge.

      This crank will work with any number of gears. The teeth are slightly thinner than those for a 5/6-speed drivetrain, but I have been using 10-speed chainrings on my new bike with a 5-speed freewheel and chain with no problems. The main point is that the clearance between arm and large chainring is a little larger, so that the chain does not rub on the arm when you a riding in the largest gear. (The smallest cog on a 10-speed cassette sits further outward than it does on a 5/6/7-speed drivetrain.)
