3T Arx II Team Stem. Never resting on their laurels, 3T has engineered an updated version of their venerable Arx stem: meet the Arx II Team stem. Constructed of 7075 T6 aluminum, it's supremely lightweight and stiff. The faceplate has been 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, in place of the twin M5 bolts used previously. The bolts themselves are now the more secure Torx type in place of the Allen bolts used previously.
