Peter N.wrote a review of SRAM Red Front Derailleur on November 24, 2011
I don't know why people gripe about the shifting with the Ti cage... I finish every climb sur la plaque and while the upshift to the big ring under power isn't quite as worry free as with Di2, I have yet to drop a chain or miss a shift with my red group. I will say though, that if you're using a light lube, the sound of the chain grinding on Ti gives me a nails-on-a-chalk-board-esque shudder up my spine. But as I was putting it on I was holding my red derailleur in one hand and my old ultegra one in the other, and wow was it lighter!
