AM120

This 90mm adjustable stem lets you set handlebar height and angle to suit how you ride, rather than living with a fixed position. It pivots through 0 to +60 degrees, so the bars can be dropped for a more forward, efficient stance or raised for an upright, relaxed one, and the setting can be changed again later without buying another part.

The body is 3D-forged 6061 alloy with an anodized finish, weighing 403g, with a 31.8mm bar bore and a 90mm extension. Two 5mm spacers are supplied alongside the stem so steerer height can be fine-tuned during fitting. Worth noting before ordering: the D5 2.0 already comes with a folding stem of this same adjustable design, so confirm your model first.
