Transition Spur Carbon MTB Frame

The All-Country Bike The Singletrack Enthusiast The Spur is our cross-country bike that refuses to be confined by labels. Now featuring 120 mm rear and 130 mm 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 The Bike For Race Day And Every Other Day Lightweight, razor-sharp, and unapologetically fast, the Spur is drawing XC athletes and performance-driven riders away from their old stiff XC bike and toward something far more capable. It delivers the precision and control to charge climbs, shred descents, and thread technical lines with confidence, redefining what an XC bike can do. On trail, it's pure Transition: lively, playful, and eager to rail corners, boost every bump or root, and turn every feature into an opportunity for fun. It's this high-energy personality that resonates with riders who aren't interested in following the traditional XC mold, they're here to forge their own line. More Travel, No Compromise. 120 mm Rear 130 mm Front The Spur now features 130 mm of front travel, optimized around the latest Fox 34 Float SL, a fork that delivers increased capability without adding weight. This upgrade reflects the evolving demands of modern XC, where courses are becoming more technical and terrain more aggressive. We anticipate this longer travel configuration becoming the new standard in the category. For everyday riders, the added front-end support expands the Spur's trail versatility, offering greater confidence and control on descents without compromising efficiency on the climbs. The Magic of the Spur When developing the original Spur, we chose a flex stay design to achieve the feel we were after. The rear end delivered a lively, responsive feel, with just the right amount of flex to enhance traction and control. The highly progressive leverage curve provides an exceptionally supple initial stroke and a surprisingly deep, controlled feel throughout the travel. This performance stood out from most bikes in the 120 mm category. For the new Spur, we've refined the design, but stayed true to what made the original so special, ensuring that the same responsive, bottomless feel remains at the heart of the bike while adding some stiffness to increase speed and snappiness.
