NUA SILICE PINION
Pure titanium gravel performance, built for adventure beyond the pavement.
The Nua Silice Pinion is a versatile titanium gravel bike designed for riders who want a capable and adaptable platform beyond the limits of race-focused gravel machines. Built around Nua’s handcrafted Grade 9 titanium frame and the durability and balance of a Pinion gearbox system, it delivers a refined combination of comfort, reliability, and real-world functionality across a wide range of gravel riding styles.
The frame offers the smooth, resilient ride quality titanium is known for while maintaining stable and predictable handling on varied terrain. Rather than focusing purely on race performance, the Silice emphasizes everyday versatility, with mounts for mudguards, racks, and multiple bottle positions, along with compatibility for optional integrated lighting systems. Internal routing and sliding dropouts allow for clean drivetrain setups and precise belt tension, ensuring dependable performance in all weather conditions.
The mechanically actuated Pinion gearbox provides a wide, evenly spaced gear range with consistent shifting performance and minimal maintenance requirements. Paired with a Gates Carbon Belt Drive, it creates a quiet, clean, and highly durable transmission system designed for long service intervals and reliable operation in demanding environments. Generous tyre clearance supports up to 700×50 mm tyres (45 mm with mudguards), allowing riders to adapt the bike for comfort, traction, or efficiency depending on terrain and riding style.
The front end can be configured with either the Nua Carbon Adventure fork for lightweight efficiency or the Nua Titanium Type A fork for a fully titanium build. Balanced geometry prioritizes stability and long-distance comfort while maintaining responsive handling on gravel routes, mixed surfaces, and extended daily rides.
Available as a frameset or complete build, the Nua Silice Pinion is a durable, adaptable titanium gravel bike designed for riders who value mechanical simplicity, long-term reliability, and versatile performance beyond race-focused designs.
