>>1901577inner bar ends as an aero position. The outer bar ends are more for climbing. You can do both.
i don't suggest any kind of aero bar though unless your bike has a smooth headset and rides really stable no hands.
Also consider if you can just lower your bars/stem, maybe flip the stem down, or get a longer stem. Especially if the bars are above the saddle height. At or slightly below is probably ideal for most riders.
>already have the bar end horns but i was thinking i could put them on the front of the jones bars.Jones bars theoretically already the front section is an aero-ish position if you wrapped it there, rather than used it all for accessories. If i had them I'd wrap the whole bar. If you wanted to be even more forward then the main position with the brakes would be cramped.
