Most likely not without modification. NRS tubes are 1.25" Nominal (1.66" OD) and DRE uses 1.5" (1.9" OD). You might be able to find a speed rail fitting (what DRE uses on their frames) that goes from 1.5" to 1.25" pipe. I think the only ones I've seen are the oar tower fittings (perpendicular to the pipe). DRE has chopped a 1.5" T and 1.25" T and welded the pieces together to make the adaption to make a seat bracket for me.
