The problem with comparing static geo numbers is sag.
Some bikes (Intense for example) like to be run at ~30% sag. Nice mid-stroke
pocket right there. Mmmmm…
Some bikes (Specialized in general for example) are happier around ~25% sag or
even less depending on how you run your fork and how hard you are going to
push the bike.
I know of at least one guy riding his Giant Reign with a coil shock at less
that 20% sag in the rear.
If the only rule of suspension setup (and it's a rule) is that the rear
suspension needs to be softer and slower (i.e. the fork needs to be run faster
and firmer) then the actual sagged numbers from bike to bike and rider to
rider can be all over the map.
I'm riding a bike right now where the rear suspension has really nice mid-
stroke support at around 30% sag but the air pressure (and how it sits into
that sag point) differs greatly depending on whether I'm running the stock
Pike (~25% sag / very light initial damper support from Charger) or the
X-Fusion I've been testing (~20% sag / lots of initial damper support from
Roughcut).
Anyways, the point is that much like looking at rates/curves without
considering what shock you are running -- or in many cases the tune of the
shock that is being run -- is pretty cursory the same way that buying a bike
based on a geo chart is…
I think the real question is what % of people read bike reviews for
entertainment and what % of people read bike reviews because they need to know
the sagged headangle to make up their mind on what luxury toy they want to
buy. I'm guessing its mainly the former?
