Light tubing, 55mm tires, adventure-ready geometry, the Purple Haze is the workhorse at Sour.
The Purple Haze is own go-anywhere do-anything big gravel bike. With its 55mm knobby tire clearance, the Purple Haze is geared up for any adventure you can dream up. With a good balance of agile geometry and all day comfort, this frame is the mainstay for all sorts of gravel riding.
Our Purple Haze has seen the world. We often look on with jealous eyes as Sour-riders take this frame all over the world on all sorts of adventures. This frame is fast and chill, quick and stable, and like a best friend, its always got your back.
All of this, built by hand in Saxony!
Adventures big or small, the Purple Haze is ready to roll.
We love the Purple Haze. This platform was one of the original three bikes we designed when Sour was still a skunkworks, and when we designed the Purple Haze, it was perfect from day one.
Since those days, we’ve refined the platform and updated it as needed. Nowadays the Purple Haze has a yoke to better support its big tire addiction, but the geometry and soul of this bike has stayed true to its very first kilometers.
Get yoke’d, not yolked.
When we were designing the current generation of the Purple Haze, we really wanted to push the tire clearance to safely fit 55mm tires. Now, not all tire and rim combinations were created equally, so your results may vary, but in general, the yoke allows the space to run straight-up mountain bike tires on the Purple Haze.
We designed the Purple Haze yoke in-house to achieve the design goals we wanted in the Purple Haze, but to also make welding easier to support our own in-house frame production.
