Choose the axle before the wheel.
OS20 wheelsets are sold with different front axle systems, commonly 10 mm or 20 mm. Match the hub axle diameter, retention style, and hub spacing to the fork. A 20 mm thru-axle hub does not fit a 10 mm open-dropout fork, and a 10 mm hub should not be assumed to fit a 20 mm fork without manufacturer-approved adapters.

The first rim question
Disc or rim brake?
Rim brake
You need a 451 rim with an appropriate braking surface, plus pads and mounts that reach that surface correctly.
Disc brake
You do not need a sidewall brake track. That opens the door to deeper, more aerodynamic rim profiles—but the disc hub, rotor, frame mount, and caliper must match.
