Left side is my chain rings.
Right side is cassettes; I click once to go up a gear; once to go down, and if I press it all the way down it will jump two gears at a time; but, only for downshifting. Here is what I'm using. Do you guys ever miss a shift and get caught in a sort of neutral pedaling?




No matter how much I read on trimming, I can't seem to grasp the what it's trying to accomplish. What is the point of the half shift? Because; when my shifts miss, the bike is just caught in a neutral state where the pedals row forward freely; sometimes the gear will "eventually" catch, and other times, I will gear up again, and then back down to get the gear I was supposed to be in. The miss-shift usually happens on a very medium cassette wheel, for flat road; so, it I wouldn't be on any extremes for cross chaining from the main chain ring.
