A few new bits in the post today, and a bit I have been working on.
Ciamillo 0G Ti brake set. Pictured below. Weigh in at 163.8grams, including the pad holders.
Not 100% sure if i will use these for the final build as yet. I might go full throttle and go AX Lightness. But these are a good start.
Next Up -
One of the things i am trying to do with this build, is tune/customise some parts myself, to make them as light as possible. I have already done the SRAM Red rear mech, and now it was time for the shifters.
This is just the first attempt, they still need final sanding and finishing. But it gives an idea of the final product. They are stock STI Levers, with BTP carbon clamps and hoods.
The original lever weighed in at 152.2grams. Mine comes in at 122.4 grams.
The only I can give to both questions is.... Yes, they probably will.
But, there is only one way to find out. The slots hopefully wont weaken the carbon to much, this isn't the most scientific of tests. But, trying to flex the paddle by hand, there is little or no movement on the material.
Looking at the way I shift, there doesn't seem to be any reason for a massive amount of force to go onto that lever anyway, but only time will tell.
Good point about the wind though. That hadn't even crossed my mind, will have to weight and see what happens.

So if there was an acoustic resonator with length = 3.3 mm (the approximate width of those slots, choosing a value to keep it simple) the round-trip travel time for sound across that gap would be 20 µsec. This corresponds to a frequency of 500 kHz, well above the ear's threshold. So those slots won't produce an audible signal.
I guess the equation is right, but my cockpit did produce a whistling sound when there was some head wind, thats why I asked.
How much weight have you shed by sanding and drilling red lever?
And I think you'd better use lighter brake options than rather heavy (for 10lbs bike, I mean) zero-G.
