I was going to do a mini review of these wheels but never got around to it so I'll post some pics I took of the same 25mm tires on both the c17 rims (Shamal Ultra) and the older Neutron rims....
Continental 4000S clincher 25mm on Shamal Ultra (17mm internal width):
Same 25mm tire on older Neutron rim. I wouldn't even think about putting a 28mm on this rim. As it is, I have to not only release the brake release to remove them, but also turn the brake adjuster on the caliper themselves as well.
And when checking dish, trueness and roundness... these wheels were as close to perfect as it gets...
Interestingly, the drive side flange is oversized yet again, and measures 82mm, versus 76mm on the new Boras, and 70mm on the pre 2015 Boras...
And they measure 22.5mm at the brake track...
Mounting the clinchers was a breeze too... by hand. Compared to my Neutrons which is quite a task to say the least. Opted for the standard clincher version versus the two-way fit version since the standard tire/tube setup is reliable and works, no matter what.
Anyway, I don't think you could go wrong with these wheels, but a 28mm tire is going to be big, so make sure you have the clearance for it.
Good luck in your shopping...
FWIW, Ribble had the Shamal wheelset as their black friday special.

I do have to agree with the above that the Zonda C 17 wheels look great @ under $400.

just wondering about wider/width... would we a non pros notice the difference in being faster on a wider rim instead of the narrow version? would you also tell the diff between an aero and a non aero frame?
You get more air volume inside the tire with the wider rim. Compared to a narrow rim at the same pressure (say 100psi) you'll have lower rolling resistance. You may also be able to run 85psi and get the same rolling resistance on the wider rim that you had on the narrow rim at 100psi - that is where the comfort thing comes in.
Very happy with my decision, absolutely amazing wheelset. I run 23mm Conti GP4000S2's and they mate to the rim just about perfectly - I wouldn't run 25's on these wheels.
