I’m pretty sure we are understanding you wgscott. When you have your trim set centered on cog 6 it will be centered on every other cog as well. And you’ll have 16 steps of trim adjustment each way. I have two rear wheels as well and mine are different maybe 4 trim steps, even the high and low are a tad different. I’m running an el-cheapo wheel right now and I can’t get it to go into the #11 cog without chattering no matter what I do, it works fine on the better wheel. So I’m gonna wear this one out then change it all.
