So Happy I bought a set of accessories in 2 colors
I purchased jockey wheels, and some other accessories and the quality and finish is TOP NOTCH and even ordered a duplicate set in another color so I can switch back and forth. Had a delivery issue on my first order with customs and Josh took care of it. I’m very happy with their products and customer service and would recommend JRC to ANYONE!
