ghost shifting

[emily_in_nc]

I'm thinking that maybe your chain is probably getting too old for you to be cross chaining in the middle ring, even if it is harder to really cross chain on a triple. Next, instead of shifting up to the big ring, try using a little FD trim when you want to use the small cogs/middle ring combo (like a 1/2 shift with the front shifter). See what happens.

I'm going to measure my chain for stretch too.

I am not sure I can do a half-shift in the front. These are mountain-bike shifters (XTR rapid-fire). I could always half-shift on my road bike with either Shimano or Campy shifters but haven't noticed that I can do that on my mountain bike.

Thanks!
