Easton quietly introduced its dual-threaded spoke interface with its AM/DH Haven and Havoc wheels. The secret is an aluminum nipple that threads onto the spoke, and also has external reverse threads which screw into the rim. The arrangement frees Easton to eliminate holes in the rim bed which would normally have to be sealed with air-tight tape or a special rim-strip (ala Stan's NoTubes).
The following video explains the benefits of Easton's dual-thread spoke technology:
With the world's most respected DH racer on the development team, Easton's wheel program is on "rock and roll." Insiders say that Easton is working hard on a carbon DH wheelset, so keep your eyes peeled in the pits for prototypes.
