Been there, done that. What you may be experiencing is tire rub due to having too wide a range on too short a bottom bracket spindle. I'm guessing you've got big tires, big gears, and a relatively short spindle. Here's more info. From Riv's site:
If you're using a Silver crank with a "MTN" front derailler, get a 113. If you're using a road front derailler: 110mm. If you're squeezing a big tire onto a Clem and want a little more chain clearance in the low gears, get a 118; It'll work perfectly. If you have a GUS or SUSIE hillibike with a tire up to 2.5-inches, you'll need a 123 with the right-cup spacer. Wider than that, get the 127. Be prepared to struggle finding a front derailer that'll shift out that far. The derailer-makers are going to doubles.
