The All-Country BikeEffortlessly explore, seek, and pursue the mountain in ways you never imagined. The Transition Spur provides a sense of connection to the bike as if it were an extension to your body. Fast and efficient with an anti-gravity feel and laser-pointer precision that begs you to climb more, go farther, and descend anything you may encounter along the way. You'll instantly appreciate the free speed you're awarded while accelerating where you're usually accustomed to pedaling. Don't judge a book by its cover though, with all these lightweight and uphill oriented character traits the Transition Spur requires no adjustment to descend like you're used to, you might actually go faster.
