Title
THE SINGLETRACK ENTHUSIAST
The Spur is our cross-country bike that refuses to be confined by labels. Now featuring 120mm rear and 130mm front travel paired with our famously progressive geometry, it blurs the lines of traditional XC. It's fast enough to race, tough enough for downcountry, and versatile enough to pull trail duty after hours. The Spur's broad range doesn't compromise performance in the category, it delivers across the board, making it the perfect ride for true singletrack enthusiasts.
