I just bought my first road bike the other day. Before that I had a hybrid, which worked pretty well when I made some changes. The hybrid had a long chainstay, like 440 mm. Even then I had a problem with pannier heel foot strike, but I'm having a new problem with my road bike. I started performing the recommended adjustments to fit my bike, and found to get my knee over the pedal at 3 and 9 that I had to move the seat back. After doing that and readjusting the seat height I noticed that the back of my foot hit the derailleur cable (the extra portion out of the bolt) and sometimes the derailleur itself (when it was in the smallest cog). Is this normal? I've never heard of anyone else having this problem. I think I have the right size frame (the biggest one available - 64 cm C-T) for me. I'm 6'5" with a size 12 foot. Someone previously recommended true cycling shoes, as they tend to have heals that don't stick out like the trail running shoes I'm using. I don't know if this will be an issue while riding, this was all while stationary on the bike trying to fit everything. Any other recommendations?
