3T Arx II Pro
$79.99
3T's Arx II is a subtle refresh of the well-liked Arx alloy stem, which has found a place on every sort of bicycle since its launch in 2007. The faceplate is drawn in tighter at top and bottom for a more ovalized frontal appearance, while retaining the cutout 3T logo. The sides of the extension are slightly flattened for a more sculpted look by comparison with the tubular section of the first-generation Arx. A single M7 bolt clamps the stem to the fork steerer, instead of the twin M5 bolts previously used, and the Allen bolts used on the original Arx have been replaced by no-strip Torx bolts. - Stack height: 40mm - Weight: 135g (110mm)

Cable grooves on the underside provide a smooth feel when you're on the tops.
