A beautifully machined stem from for those who strive for perfection
Skip to view product specifications

Straitline are a relatively new company hailing from Canada, where they machine some of the most intricate bike parts that we’ve seen.


This stem is CNC machined and has a couple of very neat features.

There’s the custom top cap that fits perfectly, and there’s the neat-looking internal wedge design, which saves your knees because there’s no protruding bolts for you to knock them on. It also stops even the most ham-fisted among us from crushing the steerer tube


The stem is available in 50-70mm lengths, is immensely stiff and does exactly what it’s supposed to.
