Rene Herse M-13 Wide Front Rack for Cantilever Brakes


Equip your bike with one of the lightest, most elegant racks ever made. The Rene Herse M-13 rack fits many bikes with cantilever brakes.

The Rene Herse M-13 rack is fillet-brazed from superlight and super-strong Cromoly steel tubing, with a plated finish for durability. The elegant tabs for mounting the rack to the cantilever bosses are brazed into the ends of the rack support tubes, like dropouts on a classic bicycle frame. (Other racks often use plates welded to the ends of the tubes or just squeeze the tubes and drill a hole.) At 180 g, the M-13 Extralight is one of the lightest racks available today.

The wide version fits bikes with wide tires and generous clearances between fork crown and tire. It requires a distance between fork crown and centerpull bosses of 100 mm. If your bike’s specs are different, we recommend the adjustable Rene Herse UD-2 rack.

The optional ‘standing’ light mount that gives you a choice among a wide range of lights. Use with Rene Herse Light Mounting Bolt. Or choose the Also available without light mount, with two eyelets that allow mounting a light on either side (or both) using the Rene Herse Light Mount.

Made in Japan. 10 year warranty.


To determine which racks fits your bike, measure the distance from the fork crown to the cantilever bosses. Note that the rack fit can be adjusted slightly by carefully bending the diagonal supports.

The racks are supplied with custom bolts that provide secure attachment:

  • 2x M6 bolts for mounting to cantilever post with smaller-diameter M5 forward extension to hold the rack securely
  • 2x M5 domed nuts
