I have not bought anything this year that changed my riding, but I did take something from this year's technology. Since I saw that Sram XX components were running double up front (like Ritchey did in the early 90's), I figured I could do without the granny chain ring. I removed the granny and replaced the middle ring with something smaller (now 32-46), as well as replacing the cassette with one that has a broader range (12-32). I am still able to ride everything I was riding before, but have fewer chain line and chain suck issues. I have just had to get used to different gear combinations to achieve the same results.
