Rene Herse UD-2 Cantilever Front Rack


A superlight rack that fits (almost) all bikes with cantilever brakes. The Rene Herse UD-2 rack is adjustable, yet elegant and strong. Made with ultra-strong, ultralight Cromoly tubing throughout, this rack weighs just 234 g.

The UD-2 rack requires a 6 mm hole all the way through the fork crown and cantilever bosses on the fork. The struts are made from CrMo steel for strength and chrome-plated for durability, so they should not be cut. Select the strut length that works for your bike:

  • Standard (150 mm) for post to crown distance (PTC) of 70-98 mm
  • Long (170 mm) for PTC of 96-114 mm


Also available in the UD-1 version that attaches to eyelets on the fork blades.

Light mount not included, available separately.

Made in Japan. 10 year warranty.

The modular UD rack system is so simple that you’ll wonder why nobody has made racks like this before. Four different struts are available to attach to cantilever posts (canti version), mid-fork or dropout eyelets (disc version).

The struts attach to the inside of the tabs, making the rack much more elegant than similar racks where the struts attach to the outside. We enlarged the rack platform slightly to make the shape come together aesthetically. Racks look much better if the rack stays slant outward a bit as they go up from the fork to the platform.

The struts are available separately, allowing you to move the rack from one bike to the next, even if one has discs and the other cantilever brakes.
