If you can have just one bike, make it Trek's 8.1 DS, and be amazed at the places you can go! This smooth-riding, adventure-loving bicycle is fast on the road, capable and confident when the path turns rough, and ready to roll from road to trail if that’s where your day takes you. It sports a lightweight Gold Series aluminum frame with multi-surface Bontrager tires wrapped around big, 700c wheels so any route you want to take is yours. And hills are no worries with 21-speed Shimano drivetrain and safe, responsive brakes at your disposal. Cycling have never been this easy or this much fun.
