On one hand you want awesome efficiency and blazing speed, on the other you want some comfort, too. Put your hands together for Felt's phenomenal Z4 Disc! This thoroughbred boasts Felt's feathery ultra-high-modulus carbon frameset that's super stiff for sprinting and climbing. It's got some tricks up its carbon sleeve, though, and you'll revel in the plush, compliant ride. To complement the sweet-riding frame you get an outstanding set of Fulcrum Disc wheels and SRAM's precision Rival 22 components with compact SRAM cranks that makes easy work of hills. Powerful SRAM Rival hydraulic disc brakes give you total control in any weather. You'll also love the quality Felt stem, bars, seatpost and the supportive Prologo saddle.
