Being a lightweight, most rims and wheels are overkill strong for me. I was thinking about getting a set of older light weight 36h tubular rims with nipple washers and building them up as follows:
Rear: 18 spokes laced 3x on the drive side, 9 spokes radial laced on the non drive side (skipping every other hole)
Front: 18 spokes laced radially, evenly spaced if the spokes holes are not offset and paired if they are
That would make an older rim originally available in 32 or 36 hole drillings into a 27 spoke rear and an 18 spoke front. This would be for crits and some road races. At 140-145 lb can I get away with this, or am I asking for it?
