Trek Emonda ALR 4 Disc Road Bike 2022
Offering pro looks and reliable components, Trek’s Emonda ALR 4 Disc Road Bike is the perfect bike for hilly sportives and long training rides. The Ultralight 300 Series Alpha Aluminium frame looks as slick as carbon and has the ride quality to match, with the carbon fork adding to the bikes great handling characteristics. Thru-axles and Shimano disc brakes keep the steering precise and braking confident, meaning more speed through corners and on fast descents.
Shimano’s 10-speed Tiagra drivetrain pairs a compact 50/34 tooth chainset with a 12-28 cassette for good hill-climbing gears, with all the cables hidden inside the frame for a cleaner aesthetic. The Bontrager Affinity Disc wheels look great in stealth black but are shallow enough to handle blustery conditions with aplomb.
