Which Sigma is Right for You?
• Sigma (19/19 Wheels) – Ideal for riders who want versatility. Whether you’re hitting trails, gravel roads, or occasional pavement, this setup provides a balanced mix of stability, speed, and off-road capability. If you’re looking for higher top speeds while maintaining off-road performance, the standard Sigma is the way to go.
• Sigma MX (19/16 Wheels) – Built for the off-road purist. If you spend most of your time on motocross tracks, single-track trails, or technical terrain, the smaller rear wheel enhances agility, acceleration, and handling. The focus here is on control and responsiveness rather than outright top speed, making it perfect for aggressive off-road riding.
