I tried Ergons a few years ago when they were
de regeur, now I prefer the offerings from
BBB. Ergofix and Ergostix are very similiar to the Ergons, minus the hype and price. And if you're considering the Cane Creek barends, the Ergostix are just as nice although not as stylish.
Since the grip and barends are separate from (but designed to integrate with) the barends, the angle of the barends can be adjusted independently of the grip angle.
I got mine from a seller on Amazon
here and
here. I don't shill for them, in fact they can be a bit dicey, but they usually have rock-bottom prices on accessories.
