Rolf Prima took their affordable Black Rock XR carbon mountain bike wheelset concept and turned out an option for roadies. The new Ares3 LS uses a full carbon clincher rim laced to their TdF2.4 hubset for a $1,399 wheelset. And it’s handbuilt at their Eugene, Oregon, headquarters, too.

The Ares3 LS has a 32mm deep rim with a 19mm internal width measurement, with a tubeless-ready design. External width is 27mm.

So, how do they compare to the standard Ares 3 that retail for $2,399? For starters, the new LS version uses steel bearings instead of ceramic; the freehub body is steel, not titanium; it has a few more spokes; and it only comes in a QR rim brake version, not disc, among other minor differences. Weight difference is +150g…but they’re also $1,000 less, and are definitely an upgrade over many stock wheels. But, it’s the same high end carbon rim, just laced to a less expensive hubset…which is exactly what they did with the Black Rock XR set.

They claim it’s just 1,515g, making it competitive with similar options that are machine built overseas. And it comes with their 5-year warranty and lifetime crash replacement program.

The Rolf Prima Ares3 LS starts shipping in May 2018. Until then, check out our factory and headquarters tour! And if you want a more affordable disc brake option, the Ares3 ES is $1,749 and makes similar substitutions to bring the price down.

Anyone know what is the idea behind the tall non-drive side flange? I’d imagine it is the opposite of what you’d want from a bracing angle perspective.

to allow the same spoke length to be used for drive side and non-drive side.

With equal diameter flanges the drive side spokes transmit the majority of the drive torque. The larger non-drive flange helps balance drive torque between both drive and non-drive side spokes. It’s correct that a taller flange increases the effective flange width but this is compensated for with flange spacing and lacing pattern to maintain good left/right tension balance.

It allows the understressed left spokes to do more work in torsion.

With a spoke cross pattern like that, the flange height matters about zero to bracing angle.

Shouldn’t disc wheels be cheaper? The rim doesn’t need a braking surface so should be easier to make
