You've got goals to demolish, and you need a bike that can help you finish a 50-mile ride charity ride, your first sprint triathlon, your daily commute, or any other fitness milestone. You want a performance hybrid that's comfortable on longer rides with big hills and versatile enough to carry groceries home after your workout.
The tech you get
A lightweight 200 Series Alpha Aluminum frame, a carbon fork that absorbs road vibration, hydraulic disc brakes for all-weather stopping power, a 20-speed Shimano Tiagra drivetrain with a wide range of gears for hilly routes, rack and hidden fender mounts, fast-rolling Bontrager R1 tires, IsoZone ergonomic grips, and compatibility with DuoTrap S so you can track your fitness gains.
The final word
If you have fitness goals, FX Sport 4 will help you cruise past them. It's the perfect combination of road bike speed and hybrid bike versatility: comfortable over the long haul, quick when you want to put the hammer down, and reliable in all weather conditions and a variety of road surfaces.
