Keeping the Forged Canti Alive, 75 Pre-Orders at a Time

A quick look at the Rene Herse canti brakes, a 75g forged wonder, and why the company is turning to pre-orders to fund the next expensive batch.

Keeping the Forged Canti Alive, 75 Pre-Orders at a Time

I find the economics of high-end component manufacturing fascinating. Take the Rene Herse cantilever brakes—they're essentially a "perfected" component, forged, incredibly light at 75 grams, and born from a Peter Weigle Concours de Machines project. But that level of refinement, especially using expensive forging dies, is a huge financial lift for a small company. So, to fund the next batch, Rene Herse is turning to pre-orders. They need 75 commitments by November 30 to pull the trigger.

It’s a very direct and transparent "put your money where your mouth is" approach, and I respect it. While the world has mostly moved to discs, there's a dedicated, discerning crowd (think Rivendell or Crust riders) who will argue, correctly, that a great rim brake is a beautiful and highly effective thing. This pre-order is more than just buying a part; it’s voting with your wallet to keep a specific kind of uncompromising, niche product alive. I'm curious to see if they hit the number.

A Few Key Specifications:

  • Weight: 75g (per brake). This is astoundingly light and speaks to the no-compromise design philosophy.
  • Construction: Forged Aluminum. This is the key—it's what makes them so strong and also what makes the production dies so expensive.
  • Tire Clearance: Clears 56mm tires (or 42mm with fenders). This confirms they are modern cantis for all-road bikes, not just museum pieces.
  • Warranty: 10-year warranty. A reassuring sign of confidence in the design and materials.
Crowdfunding: Rene Herse Cantilever Brake
To make these brakes available again, we need to commit to another forging run. That’s a huge investment and only viable if there is enough demand. That’s where the crowdfunding comes in. We need 75 pre-orders by November 30, 2025, to make this forging run happen. If the project moves forward, you’ll get your brakes in about 3-4 months. Joining the crowdfunding also locks in the old price. Once we get the new production run, the price will go up due to inflation and tariffs. What if we don’t reach our goal? Then you’ll get a full refund by December 15. (If the project goes forward, sales are final. No cancellations or returns, please.) Thank you! Goal: 75 Current: 41 Click here for more information on the brakes and the crowdfunding effort. You never knew cantilever brakes could be this good! Smart design, top-spec materials and precision manufacturing bring you smooth, powerful braking performance – and at 75 g one of the world’s lightest brake (with pad holders, but without pads which get lighter as they wear). The mechanical advantage is optimized to work equally well with modern ‘aero’ or with classic ‘non-aero’ brake levers. Forged arms are thin without giving up strength. Post-style pad holders allow simple adjustment for pad wear without the need to re-set toe-in. Carefully equalized springs eliminate the need for tension adjustment screws. Thin straddle cables with pivoting mounts ensure smooth, slack-free braking. Super-grippy ‘salmon’ Kool-Stop pads for better stopping in wet and dry conditions. To mount the brake pads, we offer two options: Direct mount without washers, with ultralight aluminum nuts for the eyebolts. To adjust the toe-in, bend the arms slightly. This version is intended for framebuilders and confident mechanics. Washers that set the toe-in, with thinner steel nuts for the eyebolts. To adjust toe-in, swap between straight and 2.5º angled washers to compensate for the alignment of your frame’s cantilever bosses. Direct mount brakes can be converted to washers with our Toe-In Washers and Nuts if you change your mind. With both methods, you adjust the toe-in only once. Then you can change the brake pads without having to adjust toe-in again.   Note: To work with the ultralight design of these brakes, the height of your frame’s cantilever posts must be within standard tolerances. (Your current brake’s pads should be roughly in the middle of the slots.) If the pads of your current brakes are at the top or bottom of the slots, the Rene Herse brakes may not fit on your frame. Pro Tip: Most cantilever pivots on the market today were originally made for production mountain bikes, where low cost was the major consideration. Their dimensions are not always accurate, and the material can be soft. If you are building a new frame, we recommend using precision-made Rene Herse cantilever pivots. Sold as set for one wheel, to give you a maximum of flexibility when spec’ing your bike. Each brake comes with all hardware and a Rene Herse straddle cable yoke.
