The AO SL fork offers the perfect balance between lightness and durability. During the design process, two main principles were followed: it had to be extremely lightweight and reliably strong. The lightweight aluminum construction not only reduces overall weight but also significantly improves maneuverability.
The fork is forged from a single block of aluminum, providing exceptional strength while keeping the weight to a minimum. AO's engineers designed the geometry with L-shaped legs to increase structural rigidity across the entire fork. The 6000-series aluminum has undergone T6 heat treatment, ensuring high durability. With a total weight of just 315 grams, this is AO’s lightest fork to date.
The fork design accommodates wheels up to 125 mm in diameter, while the 24 mm hub width fits the most common industry standard. The 160 mm fork tube length ensures a precise fit with most headtubes, and the threadless design contributes to enhanced structural stability in compression setups. The geometry and material structure have been optimized to distribute bending and torsional forces as evenly as possible — which is especially crucial when using larger wheels.
If you're looking for a precisely engineered fork that's both lightweight and strong, the AO SL is an excellent choice for your next setup.
