I have an older model (~8 years) and one of the wheelbase arms broke off. DXRacer was responsive to my email question and told me which base would work with my model. If you're looking for parts, the links can be found in the FAQ question: "If my chair's warranty has expired and I need to purchase corresponding parts, what should I do?"

Easy to assemble. The delivery was super fast and came before expected.

Honestly, I've had my dxracer since 2012. a while back the mechanisms for my chair was still broken and I'm still glad that the dx racer still provides these parts because I get to enjoy my chair with just specifically big and tall! I can only hope that my chair continues to stand the test of time and then take racer continues to have these accessories as they are top quality!
