My Merida Cyclocross 3 bike has a double chainring at the front. After a few weeks of being a little annoyed about the awkward shifting when going up steep hills, I realized that the front shifter and derailleur actually have three positions. This means I basically have to shift twice to properly move the chain on the front chainring. If I only shift once, the derailleur ends up in some kind of chain rattling limbo state until I shift again.
Is this normal? If not, what should I do about it?
