JAVA Siluro6-Top 12s is a state-of-the-art road bicycle built upon the celebrated Siluro6 platform. This upgraded model elevates performance to a whole new level with significant component enhancements designed for serious riders.
Shimano 105 R7120 – 12-Speed Performance
The Siluro6-Top 12s is now equipped with the latest Shimano 105 R7120 12-speed shifters, front and rear derailleurs, delivering crisp, responsive, and highly precise shifting. Whether accelerating on flats or tackling steep climbs, the advanced 12-speed drivetrain ensures seamless gear transitions and optimized power delivery.
Shimano 105 Hydraulic Brakes
Replacing the previous braking system, the bike now features Shimano 105 hydraulic disc brakes, offering superior stopping power and refined modulation. The hydraulic design guarantees consistent braking performance in all weather conditions—giving riders confidence on technical descents and long-distance rides.
Thru-Axle System
The Siluro6-Top 12s also benefits from an upgraded wheel system featuring 12mm thru-axles, replacing the older 9mm quick-release setup. This enhancement provides greater stiffness, improved handling, and increased stability, making the bike exceptionally reliable during high-speed sprints, rough road surfaces, and extended rides.
