For riders seeking the roads and trails less travelled, FSA’s AGX components offer the best performance for Adventure, Gravel and Cyclocross. Featuring products solidly built using advanced carbon composite and metal alloy technology, coupled with the state-of-the-art manufacturing processes, the AGX group of components and wheels showcases the range of FSA’s advancements in product development.


Hand-built and highly versatile, the tubeless-compatible SL-K Light Off-Road AGX wheels spin on advanced carbon fiber rims. They’re just 1,500g a pair and at 26.1mm wide and 25mm deep, the rim strength is superb. The asymmetric design is so deep it’s nearly square. The SL-K Light Off-Road AGX wheels are also compatible with disc-equipped cyclocross and gravel bikes. The front hub takes 9mm QR or 12mm and 15mm thru-axles and holds 24 straight-pull spokes in a two-cross pattern. The 24-spoke rear hub boasts a 6-pawl aluminum freehub for instant engagement and runs on a double row of bearings. It’s available for Shimano 9-11 speed or SRAM 11-12 speed and compatible with 135mm QR and 142mm thru-axles. Includes alloy QR axles, sealant tape, and tubeless valves.
