I am seriously contemplating a bike change in the near future. I have always rode Shimano components (105 and higher) and have generally been happy. However, my current bike, which is equipped with full Ultegra 6700 (except the crank which is an FSA SLK-Light carbon) has been rather disappointing. Without going into all the details of the issues I've had, I am now considering a switch to SRAM...likely the Force gruppo. For those of you that are currently riding SRAM, what do you like about it? What do you dislike about it? I have yet to actually test ride a bike with SRAM, but that is on my immediate agenda. What I am interested in most, is in regards to shifting. With my current bike, I am constantly dealing with extremely hard/stiff shifting. Before anyone asks, yes I have had the bike looked at numerous times, and even had my shifters replaced under warranty. My main issues occur whenever a shift involves the brake lever - so downshifting the rear cog, or upshifting to the big ring. It is my understanding that SRAM does not utilize this technique, and uses a "double-tap" system. Can somebody explain how this works, exactly? Is there no brake lever involvement with SRAM shifting? Thanks!
