Simple, dependable Cro-Mo MTB frame from famed manufacturer Diamondback. Build this up as a modest commuter or a big burly street basher.
This frame rides well and can take a whole lot of punishment (if that's your thing). It's probably older than you and will still be around when you're deep in the ground. Also has an understated yet eye-catching black and purple colourway.
This is another of those longish geometry vintage MTBs so would be a comfy ride for the taller rider. We've seen a few tasteful rebuilds of this exact frame on the 'gram and they always look great. Set of Maxxis tyres and a rack on the front is all you need. Or maybe something more imaginative? Either way if you've got the dosh we can make your dreams come true.
