Chain brushes derailleur I just got my ever first road bike, Revenio 3.0. I'm so excited. Already got my ever first road bike injury as well - those damn cleats are hard to unclip, springs on those shiny new pedals are too tight. Anyway, I've noticed that when both rear and front shifters are on their lowest gears (rear - all the way to the right, front - all the way to the left), the chain brushes right side of front derailleur and makes that 'whoosh' sound. That's not right, isn't it? I'm thinking if it's something very easy to adjust, and I can do it myself, or better to take it back to the store? _Also, can you guys tell me about common problems of bikes of this series or Raleigh road bikes in general that better to know?_

Derailer adjustment is easy - at least in theory. When it comes to fine adjustment you may find that you cannot easily get this problem fixed without making something else worse - i.e. its a compromise. Its a good opportunity to learn how to adjust derailers- make adjustments slowly, one step at a time, and count the turns so you can go back to the start if needed.

Given you should not be spending any time in this gear combo, and its not really doing any damage to the bike components, one option is to leave it alone and learn to switch to the smaller chain ring sooner.

It is worth taking it back to the bike shop and seeing if they can tweak it, but do make it clear to them that you do not want to compromise gear shifts to get it fixed.
