The Epic Extreme had the low mount swing arm cable guard. The TRX 32 has a high mount straight carbon cable guard rod. The Epic Extreme had a perimeter weight in its traditional single cam. The TRX32 just has a " Team Realtree" sticker affixed to the cam where the perimeter weight once was.....

...and, actually, the shockstop system was available on the Epic Extreme as well.

I think those are the only differences and I hope this helps.

Oh...I almost forgot...the most important....the TRX32 is about $100 less expensive than the Epic Extreme.
