COMPLETE BIKE £499
The Steamroller was designed as a dedicated fixed-gear, but its geometry is closer to a road bike than a track bike. It’ll take tyres up to about 38mm. Its got nothing in the way of braze-ons except a set of water bottle cage mounts.
The frame, like all Surly frames, is made of 4130 CroMoly steel. Steel is springy and durable, providing a ride feel you don’t get from aluminium or carbon fibre, at a price titanium can’t match. True, Surly frames are not the lightest out there, but then they’re not supposed to be. Instead, they’re a balance of excellent ride quality and durability.
For 2011 Surly have changed the component spec of the complete bike. Wider tyres, a wide upright-ish bar and chose a gear ratio more suitable to paths as well as roads. It sports Surly hubs (the rear is outfitted with Surly fixed cog and lockring, and is threaded on the other side for a singlespeed freewheel should you want to run one) and the new Open Bar handlebar, in addition to a selection of components designed to work well and love you long time without punching you in the wallet.
As you’ve probably noticed, there are a whole bunch of fixed-gears out there nowadays, most of them either actual track bikes (not especially suited to streets and definitely not suited to paths) or modified fixed-gears that people ride like BMX bikes. The Steamroller is more like an all terrain fixed-gear, an updated version of bikes from the old days, long ago, when all bikes were fixed-gears, when people raced on flat oval dirt tracks, and when bad roads were the norm. The Steamroller is right at home in these conditions.
