Surly Midnight Special

2026 · 700c wheels · 8 sizes

Steel all-road bike built around 650b x 50 mm tyres, with 700c x 42 mm as the alternate size (without mudguards). The current complete bike ships on 700c wheels; the older 650b build and the frameset share the same frame geometry. Fork offset is 50 mm on the 40 to 54 cm sizes and 40 mm on the 56 to 64 cm sizes, and the two smallest sizes have a 70 mm bottom bracket drop instead of 65 mm.
