I eagerly read this review as well. What with having the new MTB and riding it a lot more, I've made the decision to put a power meter on it. I mostly just want it for tracking Kj and TSS though, not for actually doing structured work or anything. As such, I don't really want to spend a ton of money on it. The bad news is there aren't a lot of choices for mountain bikes for the $500-700 I'm willing to spend except the single-sided variants like Stages and 4iiii. I realize those are fine but, as I've said many times before, I'm a data nerd through-and-through and just can't bring myself to buy a single-sided PM that, by it's very nature, has to make the assumptions they do. All that's a long-winded way of saying I'm actually very interested in possibly acquiring one of these for the MTB once the mountain bike version comes out this spring.
