If you're riding more aggressively on the trails, you'll want wheels that can withstand the demands. The FSA Gradient Alloy ENDURO i30 Boost 29" Wheelset is designed for enduro use and abuse. The wheels have an asymmetric spoke bed and a 23mm rim height that results in a more compliant ride and increased durability. The rims are tubeless-ready so you can ditch the tubes and add sealant and tubeless valves for a smoother ride, better traction, and fewer flats. The hubs roll smoothly and engage quickly so you can go from coasting to pedaling without missing a beat.
