The Nua Silice is a versatile titanium gravel bike, equally at home on fast gravel rides, long-distance tours, mixed-surface commutes, or multi-day adventures. For 2026, it’s been refined to deliver enhanced versatility, performance, and comfort.

Wider Tyre Clearance
Now compatible with up to 700x50 mm tyres (or 45 mm with mudguards), the Silice offers more grip, comfort, and confidence on technical trails, loose gravel, or long adventure routes.

T47 Bottom Bracket
The oversized T47 threaded bottom bracket increases stiffness and efficiency while retaining the reliability of a threaded design. This improves power transfer, durability, and serviceability.

Geometry: Standard or Custom
Available in carefully designed standard sizes or fully custom geometry, the Silice balances stability and agility: confident on gravel descents, comfortable for long rides, and responsive on technical terrain.

Rohloff, Pinion & Gates Belt Drive
Choose a Rohloff Speedhub or a Pinion gearbox, both options fully compatible with the Gates Carbon Belt Drive. The result is a low-maintenance, silent, and durable drivetrain, perfect for demanding mixed-terrain rides.
