The Big Trail 500 is designed to deliver serious fun on technical terrain. Its updated frame geometry, with a slack head angle and extended reach, gives you the confidence to take on steep, rocky descents, while the steeper seat tube angle ensures efficiency when the trail points upwards. The RockShox fork provides 140mm of smooth, responsive travel to absorb trail chatter and bigger hits.
The bike’s 29" wheels and grippy Maxxis tyres give you plenty of traction in the corners and over rough terrain, while Shimano MT410 brakes ensure consistent stopping power when you need it most. The 10-speed Shimano CUES drivetrain offers a wide range of gears, making climbs easier and descents faster. Whether you're exploring local trails or hitting more technical routes, the Big Trail 500 is built for the ride, offering a great balance of comfort, control, and performance.
