I'm looking into trading my GT Sensor X Clone (2014 Sensor Expert converted to a Sensor X Pro) for a Guerrilla Gravity Megatrail. I've actually been saving up for a Shred Dogg but this Megatrail just popped up and is in my price range. I've read that the only difference between the current Megatrail and Shred Dogg is the shock in the frame. Is this true for the older frames as well? Can I convert a 2017 or older Megatrail to the Shred Dogg by just changing the shock?
