I’d be curious. REI says it’s an aluminum frame, but diamondback lists it as “alloy”. So I’d guess low grade steel and heavy as hell. The fork looks chunky, like a drop-in replacement for their shock fork. About half the cost of a hotrock, but no rack or fender mounts.
They also have a new “podium 24” which is aluminum, but which brings the cost right back in line with specialized or trek. The insight may actually end up being heavier than the octane (their MTB) which is also aluminum, but they might be overbuilt enough that the materials are a wash. It does kinda make me wonder how they’re positioning things, why they’re specing them the way they are, and how they determine pricing. I guess ~$300 before discount is just where they want to be.
All that said, I’ve seen worse and it might end up being a decent choice and relatively budget-friendly.
