Noise pollution (brake squealing)

[rogerspam]

I've thoroughly enjoyed my new bike experience--mainly the feeling of free speed of deeper profile carbon rims (BTLOS). However, the sounds with harder braking going downhill .... is this just the price you have to pay for the fun?

I have eeBrakes on BLTOS arc groove rims. New rims when I got them.
I've switched brake pads ( I'm currently using ZIPP after starting with Campy Red) and slightly adjusted the positioning, cleaned rim and pads--not much difference noted. Have a couple other options to try (thanks to a fellow PLer who had some different carbon rim pads). The stopping power is fine but the amount of squeal is disconcerting at times and I feel "bad" making so much noise.

Previously was riding Fulcrum aluminum rims/Shimano brakes and pads as a comparison.

Toe in your brake pads. Use a business card under the front of the pad, maybe fold it in half if more toe in is needed.

That's a feature not a bug, warns pedestrians and cyclists.
Uncheck MAFAC compatibility when ordering the wheels
if you don't like it.

I like to use a small washer and a thin strip of electrical tape so I can have both hands to adjust pad angle and tighten etc. especially with canti setup it is helpful.

Initial adjustment results are promising--less squeal with hard braking on the flats. Will have to do actual downhill testing this weekend.

It turns out Christopher Walken was right--more toe-in than I thought was needed. Using tape is a good tip.
