Half radial spoking and the new Dura-Ace wheels
rothgar- Doing it Shimano's way can even out the spoke tensions. BRBR
Not exactly. Building a wheel 1/2 radial left side, 1/2 radial right side, all radial or all cross, for a true round tensioned and dished wheel, the spoke tension would be the same in all cases. The ONLY way to 'equalize' spoke tensions on a rear is to move the spoke holes over(ala OCR rims) or move the left flange toward the right.

The ONLY way to 'equalize' spoke tensions on a rear is to move the spoke holes over(ala OCR rims) or move the left flange toward the right. There is another way to get equal spoke tension with regular hubs and rims. Build the wheel with no dish and use offset chainstays to compensate for the rim not being centered with the hub. This was done by ATP Vision (while they were still in business). -- Tom Sherman – Quad City Area

jim- the shimano 7700 wheel is actually pretty close to even tension, on 4 of
the non-drive side spokes at least BRBR Mostly because the center to flange on the left equals the right. Peter Chisholm Vecchio's Bicicletteria 1833 Pearl St. Boulder, CO, 80302 (303)440-3535 http://www.vecchios.com "Ruote convenzionali costruite eccezionalmente bene"
