The ARX LTD Stem is the only stem in 3T’s road line made from carbon fiber. The end result is that the ARX LTD drops an additional 7g of claimed weight compared to the closest alloy competitor in the Italian manufacturer’s component armada. The LTD model’s carbon construction also means that it’s the stiffest stem in 3T’s line, so you’ll be that much more efficient when you’re hammering out of the saddle and every watt lost to a flexing front end is one less you have to cover moves or launch your own attack.
