DEVELOPED WITH THE Athertons, this is aimed at hard riders with a gravity bent. At 174g it’s not light, but it has a solid construction. The hardware is all 5mm bolts, which are greased rather than threadlocked.
We’ve never had issues with bolts coming loose on a properly fitted stem, so we’d rather have the ease of installation and consistent clamping force offered by greased bolts. The recommended torque of 8Nm is plenty to prevent slippage in all but the biggest crashes. Installation is easy, and the alignment markings and bar roll indicator help, especially if used with PRO’s matching Atherton bar. While the stem itself is plenty stiff, the short 33mm stack height results in a little more steerer tube flex than most if mounted atop a few spacers.
