I use clip on aero bars on my main bike in order to add an extra position off my hands for comfort, an old pair of Profile Aero Lites that came with some bars for a project bike. I had a few issues with perineal numbness when first trying them out until I switched saddles to a Cobb Randee, probably because the position works better on the nose of the saddle and rotates my hips. Just a heads up that it may not be as simple as just putting them on and riding.
