What it's like to ride

Drop-bar mixed-surface geometry: more trail and tire room than the road race bike, still not a mountain bike. Handling depends on whether this is the brand's race gravel or adventure gravel. Size 53 sits around 594 mm stack and 388 mm reach, 71° head angle, 435 mm chainstays.

Who it's for

Gravel riders. CX racers should check the brand's cyclocross chart; touring riders should look at mounts and stability, not just stack.

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.
