What Viner’s mid-depth wheelset loses in acute aerodynamics it makes up for in lighter weight and responsiveness, making it a decent all-rounder for the money.
The 40mm-deep unidirectional carbon rim is certainly stiff, with base-anchored, straight pull-bladed spokes keeping everything taut and responsive. Lack of weight at the rim means they spin up noticeably quicker under acceleration up climbs or out of corners.
The small flange hubs do mean some movement when you really whip them about between corners, but overall they’re easily placed and reasonably accurate. Braking performance is fine too, which makes them a good semi-aero choice if you live, race or simply ride somewhere hilly.
The freehub has an interesting instant pull-off feature, so you can order a spare and switch cassettes without getting the chain whip out. Just be careful you don’t get filth in the delicate nylon bush internals during the switch.
