Bokeh GRX Limited

"With the Bokeh GRX, Mason have kept their promise, having designed and built a thoroughbred adventure machine. It's an extremely versatile bike capable of handling everything from fast gravel laps to epic bikepacking trips, no matter how heavy your luggage may be."

For the new GRX Limited, Shimano has created a special edition finish with extremely limited availability worldwide. It embodies the beauty of aluminium and perfectly compliments our award-winning Dedacciai aluminium Bokeh frameset.

GRX is Shimano's adventure-riding specific groupset. Designed with a range of unique performance features and ergonomics developed over several years to make adventure riding as fast and comfortable as possible.

Our builds are available with 1×11 or 2×11 cranksets, both using adventure/bikepacking tuned ratios, and the latest clutched RX-810 derailleurs to match.


  • Dedacciai, custom formed, triple-butted performance Aluminium frame with Mason Parallax2 full carbon Thru-Axle fork.
  • 1X: Lightweight M8000 11-42 Cassette / 2X: R800 11-34 Cassette
  • RD-812 Shadow RD+ clutched rear mech.

Our frame sets deserve the best components, so we put a great deal of thought into the mix of parts used for each bike build. Bars, stem and crankset are sized to match frame size choice. See Geometry chart for component sizing.
