Yo dawg! Why won't my cross bike shift better? Maybe I was just lazy when I upgraded it from 10 to 11spd and didn't follow the clutch RD instructions or cut the chain the right length!
Geeez. Chain was too long, so low chain tension. Then also you have to have that RX800 RD right on that stop dog ear tab thing. I had it jacked up way back and the set screw for the cog to cog distance was way too far.
Whoa and behold.........it'll shift better.
