Over tensioning spokes is one way to have eyelets crack. I had a rear wheel build by a local shop using Campy Chorus rear hub, Ritchey OCR rear rim and DT db spokes. The wheel had *maybe* 1000 miles on it when I found 2 eyelets cracking. Very disappointing. I'm planning to rebuild with either a Mavic Open Pro, MA2 or a Velocity Aerohead OC rear rim.
The other possible way is anodized rim. Jobst stated that rims cracked at the eyelet because of anodizing: http://www.sheldonbrown.com/brandt/anodized-rims.html I had my DA rear hub/Mavic Open Pro Blue rear rim crack too. However, that wheel had been in use for over 10 years, probably 20K miles, with no problem until I found the rim cracking around the eyelets. I suspect it was the anodizing that finally caused the crack. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
