A question.
Nice review Mike. Your work is refreshingly thorough and objective compared to much of the prattle shoveled at the masses by the "media".
And reading between the lines, I can't help but wonder if all of these FS designs aren't somehow at the mercy of the rear shock manufacturers/tuners.
Isn't an RX 29, for all intents and purposes an Epic Marathon w/ less advanced rear shock damping circuitry? Isn't that really where any real advantage lies with the Marathon? If this is incorrect or somehow an oversimplification, how so?
Further, looking at the equation from a dollar/performance ratio, with a $6K budget, isn't an "obsolete" RX 29 w/Edge XC/DT240's, A Reba Race, "Pushed" RP 23, Formula R1 brakes, and an XT/SLX drivetrain going to be lighter, less expensive [slightly] package, and likely to preform as well or better than the Tallboy/Epic?
What's your take?
In the interest of candor, I am biased, owning a sub 25 lb RX 29, sigh, that sits mostly, because it's a "stone" compared to a 29er hardtail I have on climbs.
