Bad news, but there aren’t that many ML7s around, so good luck getting it back. This won’t help you and you may know it already, but I’m pretty sure that Ozzy was originally a shorter travel Reposado, which was tested by Guy Kesteven in What Mountain Bike – or it might even have been Maximum Mountain Bike back then.
It was built super light and very fast. After he’d finished with it, I’m pretty sure Sideways converted it into an ML7 – an inch more travel – and sold it on eBay.
I borrowed it from Guy for a couple of weeks and it’s the reason I bought my own ML7, which I still have.
Anyway, fingers crossed that you get it back.
