Looking to build a set of event wheels - road races, endurance events, club race rides. Looking at Nio 30, White hubs, and DT Aerolite / CX Ray spokes. I weigh about 185 and am moderate on wheels. Question: Can I go 24 rear, 20 front, or will this be too fragile/flexy? Would a double butted spoke on the drive side make a difference? Thoughts?
