backhander
Get your tape measure out… You'll see the geometry of the Reign X is slacker, longer and lower etc… Can't argue with that! The wheelbase on my Medium Reign X is approx 3 inches longer than the wheelbase on my mates Medium ASX, and the head angle is definitely slacker.
The ASX is quite tall and short, the Reign X quite long and low… DH bikes are designed long and low for a purpose (more stability at speed generally) which is why they descend better than shorter and taller bikes.
And then the longer back end, and the Maestro suspension system (versus single pivot) go a long way towards making it pedal and climb uphills better. Though of course it is still a heavy long travel bike, so all things are relative!
I'm also noticing how you missed off the "IMO" that I had added to that sentence… There's always gonna be some bias naturally. Likewise there's going to be tonnes of people out there that could ride the wheels off an ASX compared to me being a bit tame/lame on my Reign X. Think if you rode both back to back though, you'd probably agree with me.
