Industry Nine’s New A318 Stem

After their A35 stem’s success, Industry Nine decided to adapt the 35mm clamp stem to the 31.8 platform. These A318 stems are machined in the USA, right in Asheville, North Carolina, from domestically sourced 7075 aluminum billet, come in a variety of color options – 11 to be exact! – and since all of I9’s parts are anodized in house, you can expect consistent color matching.

I’ve been riding with this stem on my Retrotec, after only riding the original, Retrotec-built 80mm steel stem and have been amazed at what the 30mm length with the -4.4mm drop has done to this bike’s handling. What is most impressive about this stem, when slammed with a 1 1/8″ cup is how it nests perfectly over the top cap, dropping the stack ever so slightly.

Length Weight Rise Degree Stack
30mm 127g +/- 4.4mm 8º 40mm
40mm 136g +/- 4.4mm 6º 40mm
50mm 155g +/- 4.4mm 5º 40mm
One Color MSRP $145 | Combo Color MSRP $160
