Why an EVO Prong
Rigid, on purpose
Just get on and ride
No seals to change, no oil leaks, no messing with the pressure. Perfect for endurance rides or monster gravel bikes.
Room for big rubber
Tyres up to 3.2" (81 mm) on a 27.5" wheel and 3.0" (76.2 mm) on the bigger sizes, and one of the few carbon forks with room for a 32" wheel.
Suspension-corrected
498 mm axle-to-crown, so it drops onto frames designed around a 120 mm fork without changing the geometry.
Light and stiff
680 g of carbon with a tapered steerer and 15 × 110 Boost axle. Direct-mount disc, internal hose routing.
