Great thread. Thanks to all for all the info. Wanted to contribute a little bit myself for informational purpose if anyone else might be thinking of a similar build. It's a Miche Racing Hub set 28H, Kinlin XR-240 rims and Sapim lasers with aluminum spokes. Build went smoothly and used a Park TM-1 for tensioning. It's my first time to use Sapim lasers previously I had used DT Revolutions, Competitions, Champions. The Sapim Lasers seemed to resist twisting more than the Revolutions. I prepped with light grease on the spoke threads and where the nipple interfaces with the rim. Seemed to work well.
F-Hub Miche Racing 28H 146g (actual) (left/right flange diameter 40mm, center to left flange 32mm, center to right flange 32mm) from Miche, not measured
R-Hub Miche Racing 28H 286g (actual) (left/right flange diameter 46mm, center to left flange 37.2mm, center to right flange 14.6) from Miche, not measured
F-Rim Kinlin XR-240 28H 455g (ERD 590) I weighed but ERD from Kinlin
R-Rim Kinlin XR-240 28H 460g (ERD 590) I weighed but ERD from Kinlin
Nipples Sapim 12mm Aluminum Alloy Poly-Ax Nipples -14G - Silver 16g
Front spokes 28 Sapim Lasers 283 MM 128g (x2 cross)
Rear spokes NDS 14 Sapim Lasers 281mm 63g (x2 cross)
Rear spokes DS 14 Sapim Lasers 279mm 63g (x2 cross)
Total weight came in at 1621g. Not bad for a training wheel.
