Nice troll 😛 but I’ll bite….
Well along with replaceable rear drops outs, it could at least mean you could swap between 650b and 26 without screwing the bike up as converting to 650b on the emerald is just a matter of swapping out the crown.
Then you could tailor one bike to different course types….something much more appropriate than having to buy two bikes because I reckon a 29er would be far far to heavy and unwieldy for most courses.
I note that Intense, Scott and KHS are all going down the 650b downhill route instead of 29.
All in all I’m hoping this turns out to be a decent fork because I’ll throw it on the pulse I intend to get and then if 650Bs prove themselves after a few seasons then I will get a 650b capable frame (if I can’t manufacture a new set of dropouts that would lower the bb on the Pulse)
