Been running a set of 2009 red on one of my race bikes, since oddly early 2009. Still running without issue, I replaced this on the main race bike with 2011 red last year. Certainly not as smooth as shimano, but I rather like it’s clunky feel, more similar to campy to me.
I’ve also had rival on the trainer/winter bike for 2 years and again no complaints. I know sram has it’s haters, but it’s done fine by me and not skipped a beat when racing. The front mechs are shite though, I’ve replaced all with ultegra on all bikes.
Is it more betterer than shimano or campy; no probably not, but it’s working fine for me and looks great!
