Today, a frame with plenty to say: for its tenth anniversary, JRI Fixed released the Grit and sent me a frame to support my new build. Planning a dream bike is one thing; making it real is another.

What is this frame for?
The Grit was designed for tracklocross and freestyle. With a freestyle fork, it offers barspin clearance; the room for different tyre sizes and the brake-mount options make it a versatile starting point. Check the actual frame and fork’s compatibility before choosing brakes.

Lightweight
Easy enough to carry on your back, as you can see. The appeal is that mix of lightness and stiffness. This one deserves to be ridden, not left on a shelf…

A closer look
There are details on the Grit that are hard to resist: TIG-welded and brazed tubing, a raw finish and oil-slick colours around the welds. It looks like it has nothing to hide.
The Japanese decal reads “バイク”—baiku, or “bike”, as @spooky_tsuki taught me. It suits the frame’s raw character.
Here are a few close-ups. The dropouts were still burning when we took it out of the box. Obviously 🙂







Where to find it
I found this frame in the JRI Fixed online shop alongside other frames, complete bikes and components.
