Is it possible to adjust the rear derailleur as far as positioning goes? I was thinking of moving mine further back and if possible in closer to the wheel. A couple of times (and i am not positive) i thought the back of my shoe touched the derailleur.

Dropout configurations are pretty standard as far as the derailleur mounting bolt relative to the rear axle. Campy has a specific set of dimensions in their literature that comes with the rear deraileur.

The derailleur obviously can't be moved closer to the wheel. The range of travel is limited and it has to move across the entire range of cogs. Ever noticed how close the pulleys are to the spokes in the largest cog?

If your heel hits the rear derailleur, I would think it would be constantly hitting the resistance trainer.

Do you wear the heel edges of your shoes funny or have unusually large feet?

I wear a US size 11. I think the problem may be the reebok tennis shoes i was testing the bike with. I get real cycling shoes on tuesday so i'll see how that goes. By the way, its a 60cm bike.

There is no way your heel could be hitting the rear derailleur. I wear size 11 shoes and have 10 cm clearance between the heel and the deraileur. How could you move the derailleur "further back and closer to the wheel" - what does this mean?
