Surly Bike Size Chart
Official sizing guide for 2026
Surly builds steel bikes designed for real-world riding—loaded touring, daily commuting, gravel adventures, and everything in between. Their sizing prioritizes versatility and comfort over race performance, with generous tire clearance and mounting options on every frame. Surly uses numeric frame sizing (measured center-to-top of seat tube) and designs each size to accommodate a wide range of rider proportions when paired with the right stem and seatpost configuration.

Popular Surly Models & Sizing Notes
Specific sizing recommendations for Surly's most popular bike models. Geometry measurements shown for reference size (typically M or 54cm).
Straggler
🏔️ Gravel Bike • 2025Steel gravel/commuter bike with drop bars and clearance for 700x41mm or 650bx47mm tires. Relaxed geometry suits both commuting and light touring—riders who prefer a more upright position should consider sizing up.
Stack: 575mmReach: 378mm
Long Haul Trucker
🏔️ Gravel Bike • 2025Legendary steel touring bike designed for loaded multi-day travel with a long 1090 mm wheelbase and extended chainstays for stability under heavy panniers. The traditional touring geometry positions the rider upright with a high front end—riders should size based on loaded riding position rather than unloaded feel, as 20–30 kg of gear significantly changes weight distribution. A professional bike fit is strongly recommended before purchasing for extended tours.
