on my TMR02, since the rear is BMC's own proprietary brake setup, i'm probably stuck with that. but for my front brake caliper, i'm using my Red caliper, which is 127g. is there an aero version of it that is lighter in weight without sacrificing stopping power?

thanks~

Not sure about lighter as the Red calipers are pretty light, but check out the simkins egg and the TriRig Omega X for some pretty slippery front brakes

Have you tried Ciamilo brakes or even kcnc they do 110g-130g brake calipers.... I has Ciamilo micros they are a royal pain in the ass to set up but once you hit the sweet spot on cable length they are superb!!!

What size is your TMR02 and weight coming in at?

I have a 56cm TMR02 weighing in at 7.6kg (mix of DA and Ultegra, Venn 507 50mm carbon clinchers, Cinelli Neos bars), weighed a 56cm TMR01 and that was 7.7kg (sram Force, Zipp 303's)!

wouldn't call a standard ee aero, though they claim the more central cable position reduces drag, but it's certainly lighter than red and better power/modulation too

But would the EE be wide enough to accept a 28mm wide rim?

Yes, you set the pad holder spacers depending on the width of your rim for the best power/modulation.

ee spacers...
General spacer setups.
19mm to 20mm wide rims. Use 2 spacers on each side.
23mm to 24mm wide rims. Use 1 spacers on each side.
26mm to 28mm wide rims. Use 0 spacers on each side.
notice the gap between 20-23, the supplied spacers are quite thick which can limit fine tweaking

i substituted some thinner al washers to make the spacing just right to fit both my 20 and 21mm wide when used with unworn pads and keeping plenty of range on the barrel adjuster, they were m6 x 12mm, from pro bolt, almost indistinguishable in look from the originals

aside from weight and performance, what i really like is the ease of swapping pads, makes it fast to switch from cf to alloy wheels if the weather is grim

The front brakes should be no problem running EE brakes. But the BMC TMR rear brake is a PITA to adjust, so would like to replace with something with better modulation

also worth noting that their brake shoes are also lower stack than Shimano & Swisstop shoes IME (though I don't think they're sold with the calipers)
