Steamroller Frameset - Anxious Lavender

Surly Steamroller Frameset in Anxious Lavender is a street-ready steel fixed gear / single speed frameset built to take daily abuse without giving up clean handling. The 100% Surly 4130 chromoly steel chassis combines road-like geometry with track-specific standards, making it a strong choice for riders who want a classic track frameset that still fits modern, wider 700c tires and dependable caliper brakes.

Key design details that matter on the road and on the track

1. 4130 chromoly construction - Double-butted main triangle and TIG-welded frame deliver durability and consistent ride feel for high-mileage city riding
2. Brazed 1-1/8" threadless fork - Modern threadless compatibility with the resilience expected from a steel fork
3. Real-world tire clearance - Fits up to 700c x 38mm tires (or 32mm with fenders) for better comfort and control on rough pavement
4. Caliper brake compatibility - Fork and seatstay bridge drilled for mid-reach (47–57mm) caliper brakes, pairing stopping power with a clean, traditional setup
5. Track-ready standards - 120mm rear spacing, track-legal BB height, and track crank compatibility make it easy to build a proper fixed-gear bike without workarounds
6. Corrosion and wear protection - E.D. coating plus powder coat helps resist rust and everyday rack-and-commute damage; includes one bottle cage mount for practical riding
