3T Arx Ltd Stealth Carbon Stem

A lightweight, strong carbon and titanium stem, the 3T Arx Ltd Stealth Carbon Stem, in its 100 millimetre version, weighs just 118 grams, making it the perfect high performance cockpit addition.

Holding the handlebars firmly in place, the stem uses four lightweight and strong titanium bolts. These bolts are incorporated into the innovative clamp design, which attaches to steerers and handlebars without having to ramp the torque right up, so reducing the chances of damaging the stem, steerer or bars. This design works excellently with both 3T and other brands of handlebars.

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. A high quality stem requires a high quality finish and the Arx Ltd Stealth Carbon Stem does not disappoint. In a new finish, the Unidirectional (UD) gloss all black colour scheme ensures it won't look out of place on your road, time trial or triathlon bike.
