The Trek Domane SL 5 Gen 4 Road Bike 2025 utilizes a 500 Series OCLV Carbon frame and fork for a lightweight and responsive riding experience. Its specialized geometry and adjustable-tension IsoSpeed rear offer exceptional road-smoothing abilities. With the incorporation of Shimano 105 components and hydro disc brakes, rough roads are easily conquered, and the 700×32 tyres provide reliable grip and stability. This carbon-built bike excels in both comfort and performance.
