The Bike for Race Day — and Every Other Day
Lightweight, razor-sharp, and unapologetically fast, the Spur is built for XC athletes and performance-driven riders who want more than a traditional race bike. It blends precision climbing, confident descending, and playful trail manners into a high-energy package that thrives on modern technical terrain.
If you want XC efficiency with real trail capability, the Spur delivers.
What’s New for V2
The updated Spur combines its trademark lightweight efficiency with meaningful performance upgrades:
- B.O.O.M. Box™ Internal Frame Storage – Built-in downtube storage for tools, snacks, or ride essentials
- 130mm Front Travel – Optimized around the Fox 34 Float SL for increased capability without added weight
- 120mm Rear Travel – Progressive GiddyUp suspension with updated geo-adjust
- Geo-Adjust Feature – Adjust head tube angle by 0.5° and BB height by 7mm
- Hidden Linkage Hardware – Cleaner design and reduced debris buildup
- Fully Guided Internal Cable Routing – Quiet, clean, and easy to service
- Updated Aesthetics – Refined industrial design with a sleek finish
- Loham Hat™ – Helps keep dirt out of key pivot areas to extend bearing life
Suspension & Ride Feel
GiddyUp Suspension Platform
The Spur uses a flex stay rear triangle for a lively, responsive feel with just the right amount of flex for traction and control. Its progressive leverage curve provides:
- Supple initial stroke
- Strong mid-stroke support
- Excellent bottom-out resistance
- A “bottomless” feel uncommon in the 120mm category
The result? A bike that pedals like an XC race machine but descends with downcountry confidence.
Travel & Geometry
- Front Travel: 130mm (Fox 34 Float SL)
- Rear Travel: 120mm
- Wheel Size: 29”
- Geo-Adjust:
- ±0.5° head tube angle adjustment
- ±7mm bottom bracket adjustment
The V2 Spur increases front-end confidence and descending control while maintaining exceptional climbing efficiency.
