A classic, redefined.

Launched in 2007, the original 3T ARX stem appears on virtually every genre of bike from road to mountain. A strong, versatile stem, the ARX doesn't fall prey to gimmicks. Now, the evolution of the popular ARX stem takes form in the ARX II Team. It takes the classic, tubular design of the ARX and sculpts it with slightly flattened sides and a refined faceplate.

The ARX II Team stem's faceplate crimps in tighter at the top and bottom, which results in an ovalized appearance. However, even with the new shape, 3T was still able to retain its hallmark cut-out logo. This generation of the ARX also sees a more precise installation process. Instead of a traditional four-bolt Allen assembly, the ARX II features a Torx assembly at the faceplate and a single M6 bolt to clamp the stem to the steerer.

The 3T ARX II Team Stem comes in 10mm increments from 70 to120mm. Each length is also offered in 6 and 17 degree rise angles, and in the colors Stealth and Black Anodized. Please note that this stem features a 40mm stack height, and that it weighs in around 120 grams in 110mm length.

  • Trimmed faceplate design
  • Slightly flattened sides
  • 3T logo cutout
  • Torx assembly and M6 bolt secure stem to steerer

Hi, does this stem come with the required torx bits or will I need to purchase them separately?

No, you'll have to get the required bits separately. This item only comes with the stem and bolts.

no nonsense and pretty

I've put it through the wringer

This is a solid stem with looks to match. I used with wtih 3T's Ergosum and it was a very nice setup. The only thing I recall not liking about it is 3T cutout makes a 3T dirt mark on the bar.

Why Torx bolts????

I've put it through the wringer

Stem looks nice and seems to function just as well as the other 3T ARX I have had (six of them), which means great. BUT why make the stem with Torx Bolts??? This takes away from the convenience of the previous version which only required the rider to carry a 4mm hex to fix roadside. I am replacing all the bolts with Hex heads. BTW, the steerer bolt is not M6, it is M7x16. Good luck find a replacement

Hi FFT... Late answer but Zipp also uses torx fasteners for their top of the line stems (Service Course SL). They say, "[We] choose torx head bolts for our stems and aero bars - why? It’s simply a better bolt. It comes down to the way the tool head interacts with the bolt. Common hex tools tend to strip the bolt head if the bolt is over torqued. This is especially true with lightweight bolts. [We] wanted to be able to use a lightweight bolt with reliable performance. Bolts on stems and aero bars are critical to safety – having a reliable bolt is crucial." "The torx head is more robust than hex-head bolts and will not easily strip. Torx fasteners also were designed for use with a torque-limiting wrench (torque wrench), which is needed to achieve the precise torque reading for proper installation." And, "The T25 is becoming a go-to bolt in the bicycle industry. It’s been used on disc brakes for years {i.e, SRAM] and also is in use on chainring bolts, derailleurs and shifters. What’s more, the T25 tool is a common in bike shops or hardware stores and is readily available alone or in multi-tool sets."
