I've recently purchased a roadbike and I'm loving it. However, it has a triple chainset and I'm just a bit confused on part of the gear functionality. On my old mtb it was pretty clear. The shifter on the left had side adjusted the chainring and the shifter had a setting for 1, 2 and 3 relating to the big, middle and granny chainrings.
On my new roadbike it is similar, but the shifter allows for half shifts - i.e. the front dérailleur allows you to have a 1, 1.5, 2, 2.5 and 3 selection. I'm a bit confused on why you would want to use 1.5 and 2.5? Does it have any relation to where the rear dérailleur is positioned? I.e. to help not cross the chain? I'm guessing the 1.5 is really about using the middle chain ring and the bigger cassette gears and 2 is using the middle chain ring and the smaller cassette gears. Similarly with 2.5 and 3 in relation to the big ring?
Is this making any sense whatsoever????
