FSA SL-K MTB Stem

The -20 degree drop is designed to lower your handlebar position significantly, promoting a more aggressive, aerodynamic posture. It is ideal for riders looking to optimize their bike's geometry for speed and a forward-leaning riding position.

This stem is compatible with handlebars featuring a 31.8mm clamp diameter, which is the most common standard for modern mountain bikes. Please verify your current handlebar diameter before purchasing.

While it is engineered with an aggressive geometry often associated with time trials, its 3D-forged and CNC-machined aluminum construction provides the durability needed for demanding trail riding. It balances a lightweight profile with the structural integrity required for off-road use.

The stack height is 40mm. This measurement is important because it dictates how much steerer tube length you need to accommodate the stem; ensure your fork's steerer tube has enough clearance to match this height.

Yes, this is a threadless stem designed to fit a standard 28.6mm (1-1/8 inch) steerer tube, which is the industry standard for the vast majority of modern mountain and road bikes.
