What size Surly bike should I get for 5'10" (178 cm)?

At 5'10" (178 cm) most riders fit a 54 cm Surly gravel/touring frame (height range 168-178 cm) or a 56 (175-185 cm) on the Straggler and Long Haul Trucker - touring riders carrying loaded panniers should size up for stability, while unloaded commuters can stay on 54. The Bridge Club hybrid at Medium fits 168-178 cm; the steel mountain bike range at Medium covers the same window. With a typical 82-84 cm inseam the 56 gravel and Medium hybrid are the all-rounder picks for daily use.

What size Surly Long Haul Trucker for 5'8" (173 cm)?

A 5'8" (173 cm) rider with a 77-79 cm inseam fits a 54 cm Surly Long Haul Trucker (height range 168-178 cm, stack 582 mm, reach 375 mm). The Long Haul Trucker's traditional touring geometry has a 1090 mm wheelbase and extended chainstays for stability under loaded panniers - riders should size based on loaded riding position rather than unloaded feel, since 20-30 kg of gear shifts handling significantly. A professional bike fit is strongly recommended before purchasing for extended tours; the upright touring position is hard to gauge on a short test ride.

Is Surly sizing the same as Salsa or Kona?

Close on gravel and touring, with Surly running marginally more relaxed. A Surly Straggler 54 (stack 575 mm, reach 378 mm) is within 5 mm of a Salsa Warbird 54.5 (572/382) and a Kona Rove Medium (575/370). The Long Haul Trucker 54 (582/375) has 10 mm more stack than the Salsa Warbird to accommodate loaded touring. On mountain bikes, the Surly Karate Monkey and Krampus run similar geometry to a Kona Honzo at the same letter size. Use stack and reach in millimeters when cross-referencing - Surly's center-to-top seat tube measurement makes the numeric label trickier to compare.

Are Surly bikes true to size?

Yes, with versatility built in. Surly designs each frame to accommodate a wide range of rider proportions when paired with the right stem and seatpost - the published height/inseam ranges fit honestly. The Long Haul Trucker leans up for loaded touring; the Straggler stays true for unloaded commuting and light touring. The Bridge Club hybrid's clearance for 27.5x2.5" tires lets it serve multiple roles, so reach preference matters more than rigid sizing rules. The Cargo (Big Easy, Big Fat Dummy) sizing starts at S (163-173 cm) and goes to XL.

Why does Surly use seat-tube numeric sizing center-to-top?

Surly measures the seat tube from the center of the bottom bracket to the top of the seat tube (not center-to-center as some brands do), which is why their numeric sizes (46, 50, 54, 56, 58, 62) don't line up cleanly with brands like Trek or Specialized. A Surly 54 has a roughly 54 cm seat tube top-to-bottom, but the effective top tube and stack/reach are what actually determine fit. Use BikeSize's stack and reach comparison rather than the numeric label when cross-referencing - the Surly 54 is closest to a Trek 52 on stack height but a Trek 54 on effective reach.
