Description
Fast, clean, and ready for mixed‑surface miles.
The Purple Haze is built for riders who want a clean, lightweight and versatile all‑road setup without extras. Shimano’s new GRX 600 1×12 drivetrain delivers a wide gear range, great braking, and the mechanical reliability many of our riders prefer on long rides and rougher roads.
This build is for people who like to keep things simple: no fenders, no lights, no complications — just a straightforward, fast steel bike that feels confident on tarmac and stable on gravel. Perfect for everyday riding, fast loops, long days and everything in between.
It’s the Purple Haze in its purest form.

Steel may be the “original” material to build bikes, but that doesn’t mean it has to be old fashioned. We have all the modern conveniences including internal cable routing (brake), tapered headtube (44mm), and a threaded T47 bottom bracket.
And as you’d expect, the Purple Haze gets all the smart details to run a rear rack, fenders and all the bottles,
