ergo levers on aero bar questions

[Nutch [Bot]]

I want to try TT and have some hand me down cowhorn/aero bars. My plan is to use my record ergo 10 spd shifters. i've been told that shifting and braking might not work well due to the bend the cable has to go through on cowhorn/aerobars. i'd love to get bar end shifters...but not ready for that expense yet. any words of advice/tips/tricks/and what nots appreciated. Thanks.

Keep the rubber side down and the helmet side up.
