Slimmed-down Director style wishbone is lighter and significantly stronger than previous versions.
Sunday has always used a wishbone due to its strength over the two tube style chainstay design. We started out with the traditional style, but in 2008 we came out with the Director wishbone. This style eliminates the problematic welded on cap which was prone to cracking. The overall size of the wishbone decreased as well, so you get a less bulky, but very strong chainstay.
