A childhood friend of mine actually owns/runs grand premier in East Greenbush, i should check them out but last i checked they didn’t mount bike tires.
Actually found a guy who mounted them for something like 25 a rim i think, less if you just bought him the wheels. I could be way off on the prices, but i remember it was far less then any typical shop. He just did it in the garage at his house. He was listed on whatever website i bought the tires from as a ‘trusted’ installer. Can’t remember where he was though, somewhere in altamont i think. He did just as good a job as any i suppose, think he bent my license plate though.
