I'd recommend in Bicycle Pedaler and Outfitter in Somerset. It's a little drive for you but that shop has literally been in there for all of my 3 plus decades on earth. They're trustworthy, clearly not going anywhere. I'd get my bike fixed there many times when camping in the mountains. They'd help for free with small things. Especially if that's where you'll be riding it's perfect. https://bicycleped.com/

Otherwise Flat Tire Co's in Greensburg but I've never used them-https://www.flattire.co/
