My money is on grease ports.

[BikeFan84]

you think? for lubing the seals? I was thinking pressure release ala Fox 40 Rad pro to, to me if it were "grease" ports, something similar to the totem's speed lube system, it would have a metal look all over instead of just to the surround.

telonix too. they're testing in laguna.

Unless it's something Glenn Danzig made after the Danzig 4p album. Luckily it's not the case on that video.

Fox will be bringing out their new 40 soon and going 100% air sprung for their entire line(even the single crown forks), and now we've got X-fusion showing their fork in testing and the DVO(or whatver the name is) inverted fork; I'm anxious to try to decide on a new fork next year.

Im excited about this fork. Almost everything I've seen from XF has been stellar (especially the vengeance) so I have no doubt this will be a great start.

The full Fox air shock, that doesnt' excited me as much. After trying the Vengeance and even the Lyrik, I've really noticed the stickyness of Fox Air forks. I have doubts that they could make it as smooth as the others, especially with the larger legs ya know?

It's barely 'this year'. Good job on sucking up the hype.

We'll see how it goes. Their reasoning was that the new air spring forks (anything 2013 with 150mm or more travel) is allowing them to finally get full travel as it's more linear. Apparently they liked it so much they are dumping the coil.

Jump to conclusions much? I sold my DH frame and don't need a fork until it's replaced... next year.

You sir are a hypeochondriac and the prognosis is poor. No Internet mountain biking for you for at least 43 hours!

That was the lamest joke ever. Sorry everyone- I'm all hyped up after a fun ride- ps- that fork looks kinda neat. I did the grease port mod from Udi a couple years ago and thought it was pretty useful- cool to see it on a production fork, if that's what those are...

X-Fusion RV1

X-Fusion is well aware of the demand for a downhill fork in their lineup - the comment section of every X-Fusion article on Pinkbike has been filled with readers asking for it - and that anticipation was heightened with the February announcement that they will be working with the Pivot Factory DH Team on the World Cup circuit, with further confirmation coming in the form of POV footage of X-Fusion's John Hauer testing the prototype fork in California. We all knew it was on the way, and this coming July will see the release of their 200mm travel RV1 that is pictured here.

RV1 Details

• 26'' and 650B versions (same lowers, different crown offset)
• External adjustments: separate low and high-speed compression, low-speed rebound
• Uses X-Fusions twin-tube HLR damper
• New 'Nvolve' fork seals
• Pressure release valves
• Direct mount stem compatible
• Uni-directional carbon fiber leg guards
• 20mm thru-axle
• Production fork weight: 6.3lb (w/ uncut steerer)
• Availability: July, 2013
• MSRP $1299 USD

Twin-Tube HLR Damper
The RV1 will make use of X-Fusion's proven twin-tube HLR damper that we've become very familiar with from their Vengeance platform, although it will see some important internal refinements to better suit the fork's 200mm of travel (the Vengeance offers up to 170mm) in the form of a higher oil flow piston and a different shim stack arrangement. Just as in the Vengeance, the HLR damper is a sealed but serviceable aluminum unit that separates the lubrication oil from damping duties. It is generally agreed upon that this layout makes for more consistent damping by keeping
cavitation to a minimum due to the system preventing the oil from sloshing about inside the fork, but it also eliminates the chance of dirt and grime that has managed to get past the seals from mixing in with the damping oil. The twin-tube layout is just how the name suggests, with the damper cartridge employing a tube within a tube layout that allows the oil to flow through the compression damping circuits that are located at the bottom of the cartridge and out ports that feed into the outer chamber created by the exterior damper cartridge wall. The opposite happens during the rebound stroke, with the oil flowing in through the ports, past the check valve, and through the rebound assembly. External adjustments included rebound speed that can be adjusted via a red anodized dial atop the right fork leg, with separate low-speed and high-speed compression dials found at the bottom. Our time on shorter travel versions of the HLR damper have shown it to be a top performer that can rival anything on the market, so we are very much looking forward to having a go on the 200mm travel RV1.
