When I'm riding, I hear a repetitive noise that sounds like metal rubbing near the front cogs (apologies if my nomenclature is incorrect). I have a Specialized Ruby with a compact double (50/34) and 10 gears (12-27) in the back. I spend most of my riding time on the smaller chainwheel and use the full range of gears in the back.
So my question is this: am I wrong to use the higher gears in back with the smaller chainwheel (small/small), even on a compact double, and could that be the source of the rubbing sound? Should I instead change up on the chainwheel and down in back for the same speed/cadence? Or is it more likely that something is out of adjustment? My bike is only 4 months old, so could it still be new enough to need more frequent adjustments?
Or some combination of those things?![Big Grin Big Grin](https://forums.bikeride.com/images/smilies/biggrin.png)
