The All-Country Bike Effortlessly explore, seek, and pursue the mountain in ways you never imagined. The Spur provides a sense of connection to the trail as if it were an extension of your own body. Allowing you to be fast and efficient with an anti-gravity feel and laser-pointer precision. It begs you to climb more, go farther, and descend anything you may encounter along the way. You're rewarded with free speed as every pump and pedal stroke propels you forward while our SBG Geometry makes sure you're composed for every root, rock or switchback. Don't judge a book by its cover though, with all these lightweight and uphill oriented character traits the Spur requires no adjustment to descend like you're used to, you might actually go faster.
