SLA (Super Light Aluminum): Hardened, lightweight, corrosion resistant 6061 alloy makes this frame light, non-rusting and durable.

Tommaso UltraCompact Handlebars: UltraCompact flattop bars allow you to easily utilize all bar positions, maximizing efficiency, comfort, and reducing hand pressure.

OGS (Optimized Geometry System): Designed to put you in the optimal position, the Tommaso compact frame geometry lets you push your riding farther, while keeping your back and neck happy.

Tommaso Custom Saddle: This saddle is lightweight and flexible, allowing optimal flex over bumps, to reduce any discomfort for the rider.
