The 3T Arx II Pro Stem proves that pro level equipment can be affordable. Made from 2010 aluminium, using four durable Torx T25 bolts and weighing just 135 grams, in the 110 millimetre length. The Arx II Pro is finished in a shot peened, black anodised colour scheme.
3T Cycling Arx II Pro Stem
3T Arx II Pro Stem
Ride like a pro with the 3T Arx II Pro Stem. Following on from Arx, which first hit the scene in 2007, the Arx II is made from a strong 2010 aluminium and is an incredibly lightweight and stiff addition to any road, time trial or triathlon bike.
Moving away from the less secure, allen key bolt design, the Arx II uses four Torx T25 bolts to secure the clamp and the handlebars firmly in place. Another new addition is the ovalised faceplate that emphasises the cutout 3T logo and gives the Arx II a more streamlined appearance. A single M7 bolt replaces the Arx's two bolt design and securely attaches the stem to the steerer and means you do not have to ramp the torque right up. This reduces the chances of damaging the stem or steerer.
Dialling in the ideal position is easy with the stem's 6° angle and the 1-1/8 ” ∅ steerer means it is compatible with a wide range of road and time trial bikes. Easy to match to a range of paint schemes, the stem features bold white graphics, which are added to the shot peened, black anodised design.
