I've got this bike. I bought it for commuting/utility/and hopefully light touring. Problem is heel strike.

Thinking about getting the newer model, or just buying a frame and strip my current bike of it's parts.

But unsure if the newer model would have the same heel clearance issues. If I knew what a good minimum length would be, it would help me in my search. I looked at some of the bikes labeled as touring models on BD, and well, some of them look like the stays are awfully short to me.
