I recently built a new wheel using a Shimano 6500 front hub and
Velocity Aerohead 28H rim laced 2X.
I have broken three spokes so far. I am sure the wheel is built
correctly and spokes have sufficient tension.
A friend suggested maybe the spokes were too tight. My understanding
is that it is impossible to apply enough tension to break spokes by
tension alone. I had a similar experience several years ago with the
same configuration except the spokes were revolutions instead of
regular DB. I beleive the problem has to do with the 2 X pattern and
the stress applied to the spokes where they cross over. I can see at
the cross over significant bowing of the spoke. I measured the
distance from the cross over to the spoke holes in the hub at 1.5
inches. I have a 28H 3X wheel that measures 2 inches and has much less
bowing. I also have a 28H 2X rear wheel that measures 1.75 inches and
have not broken any spokes on that one. I believe the soultion to this
front wheel is to use 3X.
