What it's like to ride

A race-road geometry: lower stack, longer reach, steeper head angle, and short stays. It wants a committed position and rewards riders who already know their stack/reach. Size L sits around 564 mm stack and 390 mm reach, 72.5° head angle, 412 mm chainstays.

Who it's for

Racers and fit club riders. If you need a taller cockpit, look at the brand's endurance model on the same size chart.

Size guidance

Stack and reach describe the frame's cockpit envelope better than traditional seat-tube sizing. If you know your preferred stack/reach from a bike that already fits, search within a few millimeters first, then check head angle and chainstay for handling feel. See the glossary for stack, reach, and HTA.
