Specialized Sirrus X 3.0 KM

The Sirrus X 3.0 is a flat-bar fitness bike with enough tire clearance to be useful off pavement, which makes it the right answer for a lot of riders who think they want a gravel bike. The frame is A1 Premium aluminum with fitness geometry, butted tubing, internal cable routing, flat-mount discs, and Plug and Play rack and fender mounts. The fork is matching A1 aluminum with low-rider rack mounts, and it saves 1.6 lb over the Sirrus X 2.0.

Geometry puts you slightly upright without being slow: a 70-degree head tube angle and 1061 mm wheelbase on a small, which is stable on loose surfaces and still quick enough for a commute. Pathfinder tires in a 700x40C width roll fast on pavement and hold their line on hardpack and dirt paths. Braking is Tektro two-piston hydraulic discs. The drivetrain is a wide-range one-by setup, which keeps the shifting simple and gives you a low enough gear for any hill you will meet on this bike. Rims are 700c double-wall alloy with 21 mm internal width.
