You've seen it on the bikes of the Pros, now it's time to learn what makes it new and different.
The flagship fork from RockShox gets a major makeover for 2019. With a redesigned crown assembly, similar internal changes to the new Lyrik, Charger 2 RC2 damper, and two offset options, it's the fork of the future that DH racers have been waiting for.
One neat detail which can't be seen from the outside came with the decision to make a 200mm 29'er DH fork: the design team was able to increase the bushing overlap in the lower legs, which means that the chassis has more rigidity through all of the travel. A byproduct of that change is that the upper tubes are also longer, which allowed for the crowns to be redesigned. There is now a true flat crown as well as a drop crown, giving riders more flexibility with setup and adjustment with regard to bar height, head angle, and bottom bracket height. The look of the crowns was designed to have more of an aftermarket look, something that isn't factory spec.
There will be two upper crown options, one lower crown, and two lower options for 27.5 and 29-inch wheels. Unlike with the single crown forks were the offset is in the crowns themselves, the majority of the offset for the new BoXXer is in the lower legs.
The RC2 cartridge is tuned slightly differently from the one found in RockShox's single crown Lyrik fork, simply to accommodate more travel. The DebonAir in BoXXer is a little different as well with 91% more negative air volume than the preceding model. Again, the goal was to try and achieve as much of a "coil" feel as possible but with air.
"Coil really is the buzzword right now, but I think we can do a lot with air springs and tuning. Understanding the tradeoffs with friction, plus positive and negative volume, we can really make an air spring that rides like a coil." - Jon Cancellier, RockShox Product Manager
There will not be a coil option for BoXXer in 2019. Instead, there will be two air forks offered. The more affordable version is the BoXXer RC, which sports a non-bladder, IFP-based, price-point damper with compression and rebound adjustments. On the higher end is the BoXXer World Cup, which has the new Charger 2 RC2 damper. Both will have the new revised DebonAir spring.

Its a bit hard to read their fuzzy drawings but 49s are also 56mm http://www.ridefox.com/fox17/help.php?m=bike&id=806

Eh, trail/offset is likely going to come down to a thousand other variables (okay, not a thousand, but a lot). Just like anything, its a tool a bike designer or racer can use to manipulate the handling characteristics of a bike. What might work for one rider, won't work for another.
For me, its one of the only ways I can bring the static weight distribution back to what I want. CSs stay the same size to size, so by the time you get into XLish sizing, the front wheel is WAY out there and the rear wheel right under me. Lower offset brings the front wheel backwards, letting me get weight on the front of the bike a bit more easily. Its subtle, but its there, and is a valuable way for me to address a handling trait I'm less than fond of.
Anyway, like I said, its a tool. You'll see it played with a lot in the next few years, but there will likely be a range it tends to work - not a holy grail number.
