was equipped D-B spokes. Stragiht spokes were used for cheap street bike and utility/delivery bike.

I have been wondering WHY many wheels here in the USA use straight 14G (very

heavy, when 36+36 total 72 piecs), in 3X pattern. It seems to me 15-16 G with 4X pattern can hold 175 lb. rider without destroying wheels?

I see late 70's to 80's. they reduced numbr of spokes 32 +32, or even 28+28. My old Englsh bikes have 32+40, yes 40 spokes for rear wheel, to me 28 is no t enough spokes for road racers but O.K. for track (keirin) guys?

I know number of spokes has relationship with strength do RIMS, as wood filled alloy rims yerars ago, later filled with plasticfoam/fibert glass(?) I see modern clincher rims has very hardened material with such shape and design, 28 (or even less )

spokes maybe enough.

So, is there any guideline, when to use DB spokes or less numbers of spokes?

Once I had a set of wheel, build with Mavic MA-40 tubler rim, Campy Record hig/large flange hub 36+36 3X pattern, and straight 14 G s/s spokes, I thought they were too strong and urgry, so I sold them.
