Pre-order Lowside

The Lowside is the bike that gets you across town for a quick rip on singletrack, then over to the bar for a night out. It should come as no surprise that single speeds run deep in our DNA and have since day one.

Let’s take a brief jaunt down the ‘ol memory lane, shall we? Way back in ’98, we launched the 1x1 Rat Ride. It was our first frame, and, for a lot of people, a first foray into the world of single speeds. After many years and many trips to our favorite bar, the Sunrise, we decided to discontinue it. The Lowside picks up right where the 1x1 left off.

We added in some fancy new modern features like a hole for a dropper post cable, our Gnot-Boost rear spacing, and thru-axles, but don’t let all that scare you. We didn’t leave you late-adopters behind. Lowside’s Gnot-Boost rear spacing is compatible with 142 x 12mm or 148 x 12mm thru-axle rear hubs as well as 135 x 10mm QR hubs (when using 10/12 Adapter Washers). That cross-compatibility makes the Lowside a perfect parts-bin bike. If you have parts lying around, chances are they’ll work (unless you have rim brakes, those won’t work here).

Lowside also features a 110 x 15mm fork with a generous tyre clearance of 27.5 x 2.8" or 26 x 3". We spec it with 26+ Dirt Wizards and a Sunrise Bar so you have no excuse to be boring.

Hop curbs, cut through alleys, and find some shortcuts. If you’re looking for some mischief on the way to the trail, you can find it on Lowside.
