50mm deep 25mm wide carbon clincher (18mm inside tire bead width) with their cheapest hubs. Not the "high-temp" resin. Basalt brake track.
11-speed compatible. I'm using DA 9000 calipers and levers for my brakes. I weigh 150 pounds with gear.
I've got 500 kilometers so far. Last ride had about 2000 feet of elevation gain.
Using blue pads provided with wheels.
First "product review" so bear with me...decided to purchase on information here (this thread, throughout forum).
Came out of the box true, didn't check spoke tension. They did send me the wrong freehub body at first (10-speed rather than 11-speed), but two emails later and they expressed shipped me the new freehub no charge to me at all.
Braking in the dry seems reasonable. Not as secure as aluminum (especially not Exalith), but tolerable and I've never felt "unsafe." Modulation does not approach aluminum, and I definitely have to grab more lever to get the same "feel" but again, I've never felt that I wasn't going to be able to stop exactly when or where I wanted to. I'm not an experienced descender at all, and I live in Tulsa, which is rolling, but doesn't have crazy California/Colorado style descents. I have a bit of a pulse in the front wheel, but it's fading and the rim is smooth and flat. Suspect it might be the pads, and getting less as the pads are breaking in. Have ridden them briefly in the rain, but I didn't have to do that much braking. What I did do didn't stand out to me as being terrible (unlike some Williams carbon clinchers I had about three years ago with Swiss Stop yellow pads).
Stiffness seems good. No brake rub when standing. I'm not Andre Griepel or any other sprinter so who knows. What I can say is that on some downhills and the occasional switchback, the tracking is good, don't really have to consider the steering. I know that's a function of frame, fork, geometry, etc, but different wheels do feel different I think. Maybe hub and spoke design differences. I can say that they feel at least generally the same as Mavic Ksyrium SLRs I had from a stiffness perspective. I am using Shimano skewers so maybe that helps.
I use Vittoria EVO CX 23mm tires that measure out to about 25mm with 100psi front and rear. I used the same tires on some wheels that I have that use Velocity A23s (so 17mm inside bead if I recall), and they feel similar with similar pressure. These Farsports wheels are stiffer than the wheels with the Velocity rims. Ride quality with the same pressures, tires, and bike otherwise feels similar.
Aero? Who knows? I do catch my heavier friends on some downhills, headwinds (which it seems like we always have in Tulsa) do seem easier, hold speed better...I think, but could just be new gear effect (though honestly I wasn't expecting anything, but the mind is so easy to trick...)
In summary, for the price I am very satisfied with my purchase. If I paid more, I'd probably still be satisfied. Construction quality honestly seems decent, they ride as well as any other wheel I've owned (though I have never ridden any ZIPP or say ENVE based wheels). Customer service has been surprisingly outstanding. On that front, I was definitely not expecting much. When I got the wrong freehub, I thought for sure I was SOL. So, really if you can afford the wheels and are concerned, I would say that I have had a positive experience and would buy again if I needed another set of wheels.
