The spokes used are Sapim CX-ray in black with red or black alloy nipples to match the hubs. The Cycle Clinic use Sapim spokes because they are the best.
The hubs used are Novatec A291/F482 SB-SL with EZO Japanese bearings and the anti bite guard freehub body. I supply the wheels with a shimano freehub but I do have a limited stock of Campagnolo freehubs so if one of these needs to be fitted then that will always be possible. I would never say the hubs are for winter training on wet roads, because that is the way to shorter bearing life but they will cope with a shower as well. If you want a winter training wheel then I build plenty of those. There is no circlip in the freehub meaning the bearings in the freehub are replacable.
The weight of the wheelset is 1370g - 1400g depending on the weight of the rim which varies between 430g and 445g.
These wheels are very stiff. You can pick any similar depth factory wheelset on the market and they will not be stiffer (in nearly all cases they will less stiff) than these. Why is a stiffer wheel important? Less lateral flex means longer spoke life, higher torsional stiffness means improved power transfer and long spoke life (slightly). I think the longer spoke life is important as I like wheels that don't go out of true or break spokes.
If you are wondering how they compare to the Shimano Dura Ace C24 or similar wheels, well the do very well in fact and in many areas they are better:
Ways in which these wheels out perform the DA C24 wheelset and similar
1) stiffer - this has the benefits I have already described
2) higher spoke count - longer spoke life again
3) wider rim - gives a more comofrtable ride and improved handling
4) more aero dynamic - the rim has a more aero profile, tyre width more closey matches rim width and the thinner 20 CX-ray spokes actually has a lower frontal area than the 16 Sapim CX-sprint spokes used in the C24 wheels.
The wheels may not have dura ace hubs which are very good but the Novatec hubs actually perform very well too. The cartridge bearings are replacable and while the hub are not waht I would consider wet weather training hubs they do make good race day hubs or hubs for drier days. You you day when the roads are not covered in standing water and rain is driving. If you want Dura Ace hubs and I don't blame you 18F/24R builds with Pacenti SL23 rims will be available after christmas.
Wheelset weight is low and the rims are tubeless compatible. The Cycle Clinic stock all the spares needed to keep these wheels on the road.
So if want a wheelset that performs as well as (or dare I say it better than ) the best alloy rimmed race orientated wheelset on the market then this wheelset is a option you should consider.
