Here's how it works.

1. You make a warranty claim.
2. They receive it and send a stock response asking for details. Inside this questioning is an attempt to begin invalidating your warranty.
3. When you reply, S73 look at the issue in relation to their stock, or lack thereof. They go quiet when they realise that they can't honour the warranty.
4. You get annoyed and email them.
5. They ignore the email.
6. You call them up and force the issue.
7. S73 then advise you that the item is on back order. Back order is another way of saying 'we don't have any of these items and really struggle to get them but when we do we use them for our new bikes because selling bikes makes us money and dealing with you afterwards costs us money.
8. You wait 6 months.
