The Stans Flow EX3 rear wheel with DT Swiss 350 Boost hub is a top-tier enduro rear wheel replacement or upgrade. The EX3's Tiebeam triple-cavity construction is battle-tested at World Cup DH and Enduro World Series level, delivering the rim durability aggressive riders actually need.

  • Stans Flow EX3 rim — Tiebeam construction resists sidewall folding under extreme impact loads
  • 29mm inner width, 6069 alloy, tubeless-ready with Bead Socket Technology
  • DT Swiss 350 Boost rear hub with Ratchet EXP internals — specify Microspline, XD, or HG freehub
  • Boost 148mm rear axle spacing for modern enduro and trail frames

The rear wheel takes the biggest punishment on any descent — the EX3's Tiebeam brace and wide 29mm inner width give the tyre the support it needs to hold line without the rim buckling. The DT Swiss 350 hub keeps things sensible: reliable, serviceable, and available in any freehub body you need.

Available in 27.5" and 29". Specify wheel diameter and freehub body (Microspline, XD, or HG) at checkout.
