At Renouf we are aware that the most important factor when it comes to achieving your desired fitness goal is perseverance. In most cases we have spare parts in stock for the machines we sell or can at least get the parts you need. Please retain you invoice as proof of purchase. Most times we require the part in question to be returned to our warehouse as proof of the problem however other times a clear photograph will be sufficient for us to assess the issue.
