(May 31, 2022) – Shimano will have a special, collaborative exhibition at this year’s Unbound Gravel, which they asked Mariposa Bicycles to build a frame for. The exhibition will include ten stunning hand-built bikes designed by frame builders from around the world and will debut Shimano’s new GRX Limited groupset. These bikes will be on display June 2nd and 3rd at the All Things Gravel expo in downtown Emporia, Kansas to celebrate the history as well as the future of gravel cycling with a nod to the bespoke bicycle community.

Shimano GRX Limited groups will be displayed on bikes created by the following frame builders:

  • English Cycles: Steel Construction (Cottage Grove, Washington, United States)
  • Speedvagen: Steel Construction (Portland, Oregon, United States)
  • Mosaic: Titanium Construction (Boulder, Colorado, United States)
  • Low: Aluminum Construction (San Francisco, California, United States)
  • Firefly: Titanium Construction (Boston, Massachusetts, United States)
  • Chumba: Steel Construction (Austin, Texas, United States)
  • Mariposa: Steel Construction (Toronto, Ontario, Canada)
  • Seven: Titanium Construction (Watertown, Massachusetts, United States)
  • Enigma: Titanium Construction (Hailsham, United Kingdom)
  • Angel: Titanium Construction (A Coruña, Galicia, Spain)

Born out of adventure and the call to Explore Beyond, Shimano delivered the first dedicated gravel components back in 2019 with Shimano GRX. Built to support riders as they pursued a wider range of terrain on drop bars, GRX parts helped advance gravel riding and opened the door to new riders around the world. Today, Shimano releases GRX Limited to celebrate this revolutionary gravel group and the heritage of drop bar adventure riding.

At its core, GRX Limited is the tried and true 11-speed mechanical GRX 800 series groupset, but the brushed and polished silver finish delivers a classy take on the quality, precision, and durability synonymous with GRX. The limited run of parts comes in three available spec options; 1×11-speed and 2×11-speed for drop bars, and a third, special offering of 1×11-speed for flat bar configuration.

Michael Barry describes the frame he built in a recent interview with Matt Hansen from Canadian Cycling Magazine.

GRX Limited will be available solely as a complete group set, only available from frame builders and aftermarket retailers.
