The 3T ARX Pro stem is identical in almost every way to the ARX Team stem. In fact there are only 2 differences of note: (1) The ARX Pro uses a steel bolt package instead of the Team"s titanium bolts. This results in a net weight difference of 30g, with the ARX Pro weighing in at 150g. (2) The Pro has a White stripe down the side. The Team gets a Red stripe. Structurally speaking, the ARX Pro and Team are the same stem. They"re both forged for strength, and they both pass the same battery of DIN and CEN certification tests. With the Pro you end up a few extra grams due to its steel bolts, but you save a pocketful of dollars. It"s available in 10mm increments between 90mm-130mm. The stack at the steerer clamp is 40mm tall. It comes in a 31. 8mm clamp size only.
