SURLY STEAMROLLER 28″ FRAMESET

Why complicate things when they can be done simply: the Steamroller frame from Surly

The Steamroller is the bike in its simplest form – a fixie. Maybe you’re thinking now: ” Fixies are so 2008″ , or: ” Everywhere on the internet it says that I shouldn’t ride them.” But the Steamroller is different. It was built for the road with a geometry closer to that of a road bike than a track bike. Combined with its double-butted 4130 CrMo steel construction and 38 mm tire clearance, you have a tough frame that handles potholes, curbs and backyard alleys like a pro.

Manufacturer’s Notice:

When choosing your frame size you should take into account that Surly does not measure the seat tube specifications to the end of the seat tube. For frames with struts on the top tube, this is measured from the middle of the bottom bracket to above the struts. For frames without struts, measure from the middle of the bottom bracket to the top edge of the top tube.
