Does your white Aero Grand Copmes look like this??:
Personally, I really like the white on white Diacompe AGC levers as you see them on my Peugeot in the pic. I've had them on there since the late 80's and they still look brand new. The hoods are especially good as they never seem to deteriorate at all even after all these years and different conditions. I think they're made of silicone instead of natural rubber.
I think the levers are powdercoated white as the finish feels very durable, almost like the porcelain finish you find on stoves. You can send those unwanted white Diacompe levers to me if you really do not what them!
