Specialized’s Roval Roubaix 322x road wheels buck the aero trend with shallow box-section rims and lots of spokes. It may not be a terribly speedy formula but there is still plenty to like about this old-yet-new-school wheelset, especially in rougher conditions.
The aluminum clincher rims are just 21mm deep, the spoke count is rather generous at 24/30 front/rear and there isn’t a single radially laced spoke to be found. Aerodynamic performance was one of the original Roval tenets, though, and Specialized does build the wheels with bladed DT Swiss stainless steel spokes and hidden self-aligning nipples. Even so, let’s be realistic here: few people are going to reach for these when a time trial looms.
The payoff to the shallow rim and fully crossed spoke lacing is a subtly smoother ride even on washboard dirt roads or broken pavement, and the increased comfort only becomes more noticeable as the hours stretch out.
Compared to most – but not all – deeper-section rims, the softer Roubaix 322x hoops are more apt to flex over small obstacles rather than bounce off them and it’s no wonder top pros still reach for wheels like these come Classics time. Speedy they’re not but they definitely move further up the list if we know we’re going to be hitting the rough stuff.

Not just for the bumps
The Roubaix 322x wheels are confident descenders. While their non-aero rims don’t offer any advantage as speeds increase, their minimal surface area means it takes a heck of a crosswind to knock them off line – we even felt comfortable in swirling Rocky Mountain canyon winds that invariably force us to leave deeper wheels at home for fear of being behind on our life insurance premiums. More subtly, the slight amount of radial give yields a touch more grip on the road for a sure-footed feel.
Specialized don’t peg these things as climbing wheels and they spin up noticeably more slowly than lighter sets, but they’re capable ascenders nonetheless. Total weight is held to a reasonable 1,586g (712g/874g front/rear, plus 92g for skewers) thanks in part to an interchangeable aluminium freehub body and carbon-tubed front hub shell.
The generous helping of pulling spokes on the rear wheel helps put the power down with little noticeable wind-up whether climbing or sprinting. Drive internals come courtesy of the familiar DT Swiss star ratchet system (borrowed from the 240s) and though eminently reliable, it also still carries with it the languid 20-degree engagement speed.
None of this would mean anything without longevity and our Roval Roubaix 322x samples have proven durable through nearly a full year of testing. Credit goes to the excellent build, high-quality components and admirably consistent spoke tension as measured with our FSA tension meter. Moreover, Specialized’s DoubleDrive lacing pattern – which uses 20 driveside spokes and 10 non-drive ones – yields unusually even tension between the two sides.

Bumps in the road
It’s a good thing our wheels have remained straight, though, since truing them is a major hassle. In addition to the purported aerodynamic benefits, the self-aligning internal nipple system is designed to relieve spoke stress and distribute the tensile load over a larger area of rim while also requiring a smaller hole in the non-eyeletted rim – all good things in terms of durability and seemingly effective, but a serious inconvenience in terms of maintenance.
Specialized intends for this wheel to see its fair share of abuse and while we didn’t knock these out of true ourselves, someone is bound to. Given that it already has a non-aero, box-section rim, we would have preferred external nipples for ease of repair, not to mention standard J-bend spokes because straight-pull versions – let alone bladed ones – can be exceedingly difficult to source when needed.
We also ran into an unusual problem when swapping the Roubaix 322x across various test bikes. Specialized uses widely spaced flanges for the front hub to increase lateral rigidity, and at a whopping 80mm from centre to center, they might be a little too wide. Fork blade clearance was sufficient – just barely – on most models we tested but wholly nonexistent on some, including an older LeMond carbon model and even a new Trek Madone. We weren’t able to check every model out there, though, so be sure to do a trial installation if possible.

Old school is good but …
Save for the odd fork interference issue and difficult truing procedure, there is little to complain about with Specialized’s Roval Roubaix 322x wheels. They offer a comfortable and stable ride, a reasonably quick feel plus excellent build quality, and might be just the ticket for those living in perpetually windy environments as long as aerodynamic performance doesn’t sit at the top of your priority list.
All of the attributes listed above could also apply to something built 10 years ago, all be it in a less fancy-looking wrapper, and therein lies the rub. At around £679 (US$1,000), the Roubaix 322x set is rather expensive and a competent wheelbuilder could provide a comparable level of performance for substantially less money using conventional components.
While the Roubaix 322x recalls the benefits of old-school wheel configurations, the flipside is that there will be little reason for some to pay extra money for something that has effectively been around for ages already.
