I did not build them yet but I plan to build them this year.
I have the rims already they are made by ArcTech they were part of a group buy on this forum.
The parts I listed are the parts I will most likely use.
The rims are labeled and say not to exceed 100kpf of tension. For which I will adhere to.
I will add the nipple washers to spread the load.
In comparison I have re-built a pair of Mavic Helium which have the same rim as the Mavic Reflex.
Mavic calls for a tension for 92 -112 kpf in their documentation. I made them tight at 130 kpf on the rear drive side and 100 kpf on the non-drive side for the rear wheel and the front wheel at about 100 kpf on all spokes (the front is radially laced where as the rear the non drive side is radial and the drive side is 2 cross). I specked my build from another set that was factory built so Mavic actually went with a lower tension in their documentation. I used a Park tool tension meter to check the tension on all spokes
The tension of 100 kfp should be stiff enough for a rider my weight 150-160 lb.
The lacing pattern will be the same as the Mavic Helium described above.
The spokes I might go with sapim c-xray instead of the sapim lasers
As far as braking will will use the Swiss stop pads. The braking surface on these rims seems to be excellent.
The wheels will only be ridden in dry weather.
These wheels will be similar to the Reynolds Koms which I have tested although a hell of a lot cheaper.
