Trek FX Sport 5 Bike Matte Dnister Black XL

A fitness bike that's every bit as fast and capable as the race bikes found in our road lineup. FX Sport 5 has quality parts that will hold up over serious miles, but real value of this model comes in the OCLV Carbon frame: it's light, fast, and it has IsoSpeed—a decoupler at the seat tube/top tube junction that absorbs fatiguing bumps from the road so you can stay stronger longer.

Why you'll love it

1. All the performance of an advanced carbon road bike, with the comfort and control that comes from a flat handlebar

3. You can pair FX with your smartphone and send your ride data to your favorite fitness app when you add DuoTrap S
