I am using rear sets on mine, just not that far back. I found it easier to look at more modern road bikes as their foot pegs are what we would consider rear set for our old bikes or strap some pipe in a few different places to get the positioning right. I imagine you won't be doing long trips on the Tracy,especially with clip pons on it so it may be fun for around town,any way it won't be too hard to change the position of the rear sets if you decide too...I like the Tracy's, cool looking kits.
