Two years after the return of the Float X into Fox's lineup, several of the design features from that single-tube shock have trickled down into the new Float and Float SL. The Float has a fairly broad range of applications, from trail to cross-country bikes, while the Float SL has more of a laser focus on the XC / marathon side of the spectrum.
Float Details The Float uses a similar damper design to the Float X, but its inline configuration makes it 150 grams lighter and takes up less space, providing more clearance for things like water bottles.
External adjustments include rebound, and a two position compression lever that toggles between 'Firm' and 'Open' mode. That 'Open' mode can further be adjusted by selecting one of three options. The 'Firm' mode is tunable, allowing manufacturers to decide whether they want that setting to make a bike feel like a hardtail, or go with something a little more forgiving.
Inside the new Float there's a larger piston, a new valve and IFP design, and an MCU bottom-out bumper instead of the rubber o-ring used before. That bumper should help make full-travel events less jarring, a feature that'll be appreciated by all the riders out there pushing shorter travel bikes to the limit.
The EVOL air spring's volume has been increased in order to give the shock a more linear feel, and to improve its small bump compliance. There are also new, smaller volume spacers that make it possible to really fine tune the amount of end-stroke ramp up.
Sizes: Standard eyelet: 170, 190, 210, 230mm. Trunnion: 145, 165, 185, 205mm.
Weight: 293 grams for 170 x 35mm
Price: $349 - $519 USD
Float SL Details If the Float is a pared-down Float X, then the Float SL is a pared-down Float. It's 58 grams lighter than the Float, and is the replacement for Fox's DPS SV shock.
A three-position lever switches between compression modes, with three more settings to choose from in the fully open position. The Float SL (and the Float) are also available in a remote-compatible version, for riders who want to have a handlebar mounted lockout. The EVOL air spring is unchanged from the current DPS configuration – the curve of that air spring provides works well for shorter travel, XC-oriented bikes.
Sizes: Standard eyelet: 170, 190, 210mm. Trunnion: 145, 165, 185mm
Weight: 235g for 170 x 35mm
Price: $349 - $519 USD

The best example of how well thought out the x2 was is when they first came out they were exploding.
Instead of actually fixing the issue fox issued a "recall" and dropped the max psi to 250 on the early models.
The cheapest non solution they could actually do and still not get sued.
In my experience, based on fellow riders, sample size of around 6 bikes/shocks, over a time period of about 4 years, the failure rate of X2 is _zero_. But my personal RockShox Monarch Deluxe and Cane Creek DB Air IL failure rates are _100%_, since I had one of each and they both got stuck down consistently.
I'd pick an X2 all day based on this.
*(sorry DVO, no shade, just needed an example of lower quantity)
As an owner of a previous-gen X2 I get cranky when it squelches, but then I look at how much I rode it, and I generally have met the service interval. So off to get rebuilt it goes.
I'm low key relieved to see that I'm running the LV, so I guess my shock isn't nominally obsolete (yet)?
Here's Fox's explainer on how to tell them apart: www.ridefox.com/fox17/help.php?m=bike&id=675
What they don't discuss there is how Trunnion models fit into this scheme--are they all LV?
For those who aren't familiar with this problem, it's related to the fact that Specialized uses super long shock yokes which greatly increase the effective eye-to-eye of the shock. This can drive a ton of extra side loading into the shock (which it's not designed to support). This puts a bending load on a damper shaft that eventually fatigues and breaks. You can reduce the chances of this happening with proper maintenance of the yoke/shock pivots, but part of it is down to manufacturing tolerances, so you really don't know how long it will take before a failure occurs.
Do you want that? Then maybe upgrade.
No it doesn't. Everything on the Float happens at the piston, while the Float X has an entirely additional set of valves at the reservoir. Even if the piston is the same part on both, they're doing different jobs on each, and are not going to share valving of anything like that.
Not really the same difference. Float X -> Float changes the architecture, non-X loses something. Float -> Float SL just changes the weight/size (looks like mostly eyelet and maybe the air can, which seem to be held over from the DPS since they're saying the spring is the same)
