Some how Nightshades seems to come up with some STRANGE ideas!
ie... clipless pedals, but not to thread driff.
Where does it say 40? Or is it your idea that more must be better.
A good set of 32 spoke hand built wheels with quality rims and double butted spokes,
Ridden on the street, mostly smooth roads, should be fine. If you really wanted to be on the safe side, go to 36 on a Dyad rim.
Buy then you have to run a 28 tire.
But then I just said what you posted, not what you wrote.
To the OP, Look up peter white, or call joe young. Peter is an opinioned old man, that knows his stuff, but is hard to deal with.
Joe Young is a GREAT wheel builder, who is also a very nice guy.
Or look around for a local wheel builder, ask the REAL fast racers in your area. Most times they will give you a clue.
good luck
