SL-K AGX i25 700c Wheelset - XDR

The FSA SL-K AGX i25 700c Wheelset is a premium carbon gravel wheelset built for riders who want one fast, tubeless-ready platform that can cover gravel, cyclocross, and all-road duty while still holding up when routes get rough. With a modern wide rim bed, an asymmetric rim profile, and hand-built assembly, it targets the balance most mixed-terrain riders are chasing: confident tire support, responsive acceleration, and long-term wheel stability.

Why it works so well for modern gravel and CX builds

1. 25mm internal rim width (i25) - Supports today’s wider gravel and all-road tires for a more stable contact patch, better cornering support, and more comfort on broken surfaces.
2. Tubeless-ready rim design - Enables lower pressures for added traction and compliance, while reducing pinch-flat risk compared to tubes on the same terrain.
3. Asymmetric rim profile - Improves spoke tension balance for a wheel build that stays true longer and maintains more consistent feel under load.
4. Full carbon rim construction - Delivers a crisp, efficient ride character that rewards hard accelerations and out-of-saddle efforts without the vague response common to heavier wheelsets.
5. Hand-built assembly - Prioritizes build quality and consistency, a key factor for durability and reliability in high-impact gravel and cyclocross use.
6. SRAM XDR driver compatibility - A direct fit for SRAM XDR cassettes, making it a clean choice for modern 1x and wide-range drivetrain setups.
