Default front derailluer is rubbing crank.

i have just noticed after going for a ride that the right crank is rubbing against the front derailluer. i think it may have started after i went to shift to the smaller chain ring, and when i did that the chain derailled.

how can i adjust the derailluer so that it does not rub. want to see if i can do it myself rather can going back to other side of sydney to return to the bike shop.

also the bikes only 3 weeks old, is specialized roubaix comp, is a 105 component.

thanks guys.

First thing to do is check the derailleur clamp hasn't rotated on the seat-tube and pushed the cage out of alignment.

Then check you haven't actually bent the derailleur cage.

If none of these, then you might need to adjust the limit screw, check out the Park Tools website

I'll second the Park Tools site. If the derailleur is rubbing on the chain ring, it probably needs some vertical adjustment at the least.
