To make up for my response, how about this...Thank you cx, your sarcasm was much appreciated. I assumed Apex,Rival,and Force were mechanically pretty much the same,just lighter materials used ,until you get to Red. i was hoping someone had some real world experience not just a smart a$$ response for a newbee.
Just what I needed to hear, thank you!I have different bikes with the Apex, Rival, and Force group sets. About the only thing I notice outright is the Force cranks — they're noticeably lighter, but that's about it. As for shifters, I can't tell the difference. They still all make the satisfying double-tap sound.
I think you'll get a better bang for your buck on other parts (wheels, tires). In my case, losing 20 lbs of fat was the cheapest and best investment I've made, and I'm hoping to lose 20 more.
Doesn't look like anybody has mentioned a big difference for 2013-and-newer Force: it's now a 22-speed groupset. I've not heard about 22 speeds for Rival and Apex as of this time. But I think it's just a matter of time before all SRAM mechanical groups are 22 speed.
