Welcome.

I have two 7000zx and a 8000sl, (vintage MTBs) and a yet another zx frame in storage. I guess I like them. Most parts of those bikes I cobbled together with eBay used parts or cannibalized other bikes. Keep your 7000 long-term, (hybrid?) you can always use it for something. I've considered putting an electric kit on one of these MTBs once the weight and price comes down.
