Henry - Its a 36 spoke wheel of questionable quality...

MrEss - These wheels were most likely machine built and again I rally can't complain because they have served me so well over the past two years - Cyclic unloading on the non drive side is most likely the cause - Very interesting as I have been investigating this closely - A simple test has been just flexing the spokes and yes there are spokes with much less tension - I think I'll just take them all down and rebuild replacing all the non drive side spokes - But then again here I am spending 50$ on one wheel of a 90$ set...

But ya know - Its not really about the money... What a great hobby this is!!!
