The companion bars to the Moto Cruiser. They're a bit taller than our Cardinal Bars , but feature the same back sweep and upsweep, because we think it's the best. They're tall. Many older bikes had pretty low stack heights and we're not into being all hunched over in a "racer" position. So we mount these and find them dang comfy. They provide a heads up riding position for urban riding and plenty of leverage for trail shenanigans. The clamp diameter is 22.2 so you will need shims if you're planning on using a 25.4, 26.0 or 31.8 clamp stem. We recommend utilizing a stem with at least four bolts in the faceplate, you can generate a lot of leverage with these and anything less risks the bars rotating.
