AM Stem

Frequently Asked Questions

• What lengths and rise options does the Hope AM Stem come in and how do they affect cockpit fit?

  The Hope AM Stem is offered in 35mm, 50mm, and 70mm center‑to‑center lengths with 0° or +12.5° rise; shorter lengths quicken steering while longer lengths stretch the cockpit, and 0° favors an aggressive forward position versus +12.5° for more upright control — stack height is ultra‑low at 38.5mm.
• Which bar clamp diameters does the Hope AM Stem support and when should I choose 35mm over 31.8mm?

  The Hope AM Stem is available in 31.8mm and 35mm clamp diameters — choose 35mm for modern oversized handlebars and extra stiffness, or 31.8mm to match standard flat MTB bars.
• Is the Hope AM Stem durable enough for enduro and downhill riding?

  Yes — the Hope AM Stem is CNC‑machined from 7075‑T6 billet aluminum with a chamfered 6‑bolt faceplate and opposing steerer bolts, engineered to exceed EN/ISO/ASTM MTB stem standards for crash‑proof durability and fatigue resistance.
• What is the weight of the Hope AM Stem and how does that balance with strength?

  Weights vary by size from approximately 105–135g (the 50mm 0° is ~115g), giving a relatively light stem for an overbuilt, billet 7075 construction so you retain low mass without sacrificing impact resistance.
• What are the torque specs and installation features for the Hope AM Stem?

  Torque specs are: front clamp 8Nm, rear clamp 5.5Nm, steerer clamp 5.5Nm; the stem uses an interlocking faceplate, stainless hardware, and opposing steerer bolts to prevent rotation and corrosion—tighten to the specified Nm to avoid over‑loading the bar or steerer.
