Sneak Peek: Inverted RockShox RS-1 Fork 35

UPDATE: Confirmed! The fork is called the RS-1 and is indeed a cross-country mountain bike fork. Check out some images of the real deal below. Because the fork seems to include a front hub, we're inclined to think that RockShox/SRAM may be drumming up another new front hub size - possibly 15x110mm. Specs are being held until an embargo passes in April, so stay tuned for more details.

Sneak Peek: Inverted RockShox RS-1 Fork

Sneak Peek: Inverted RockShox RS-1 Fork

Back in 1989, Paul Turner and Steve Simons introduced the world to the RockShox RS-1 - the first suspension fork for mountain bikes. The original RS-1 had just 49mm of travel, but even so the thought of using suspension bewildered most riders. Greg Herbold went on to win the first Downhill World Championship aboard the fork in 1990, and Ned Overend captured the XC World Champs title the same year.

Following their big wins, mountain biking changed. As radical as it may have seemed at the time, the MTB world grew to love suspension. Rear suspension designs soon followed and things have continued to evolve to this day.

RockShox says they're ready to change everything once again...

Over the past few days RockShox has quietly been releasing teaser images of the new fork on Facebook, which we've pieced together for a bit of a sneak peek.

From what we can tell, the new RS-1 is an inverted cross-country fork. RockShox already has an impressive offering with the SID, but this new design looks to offer a much lighter package. A single piece carbon steerer/crown/upper leg assembly could bring the weight down drastically over traditional casted designs. We anticipate seeing a remote lockout as well, which may route through the top of the right fork leg.

Stay tuned for official details. In the meantime, think about how far technology has come since the original RS-1...

    I wonder if they are doing this to cut down on the number of forks they are carrying. I bet you can swap an internal spacer and make this fork work for 26, 27.5, 29. If so, would definitely make production and stocking easier on them. You gotta be thinking they wish they had a 20 mm thru axle for this beast too.

    Doubtful. Each size typically requires a different offset in order to make the bikes handle properly.

    Good point. Still, they could just press different dropouts on based on the desired wheel size, then use the same stanchions, uppers, and most of the internals. Probably would still save them on stocking and production.

    No one remembers Maverick? The SUC32 (real name)? Haha

    I was in Moab today - hoped to catch a glimpse. No luck.

    What is the point? Is it better? And if so, how is it better?

    i think trex has it right that it will fit fatbike tires and those are all over replacing 29ers

    If the strength and stiffness issue have been solved, then at least in one way it is better , is that the oil is always up against the seals, improving seal and stanchion life as well as improving small bump sensitivity. At least that what "they" say! Lol

    What wheel size does that look like to you on that Specialized?

  • Reinforcer

    3/23/2014 7:57 PM

    That bike is a S-Works Camber 29 and all Camber bikes have 29 inch wheels.

    also a new brake rotor and an all black monarch shock in that photo. hans dampf tires aren't exactly "xc". maybe it's light duty trail as well. is that a specialized camber?

  • bjenson

    where'd the photo go?

    found this one of the new rotor. dirt also had one of a new brake lever a bit ago.

    I'm just waiting for the right time to put my 02 Marz. single crown Shiver back on, this just might be the year. ha.

    It looks like it might accommodate fatter wheels possibly. Maybe I'm just crazy though.

    You guys realize this was done 15 years ago by Bryson Martin at Marzocchi. The current founder of DVO.

    Why is everyone freaking out? There's nothing wrong with upside down forks and Rock Shox does a ton of R@D. I'm guessing that XC riders will love them and they could be a precursor to an upside down enduro or maybe even a DH fork?

    "A single piece carbon steerer/crown/upper leg assembly" - similar to what Marzocchi and Easton tried with the Bomber RAC about 15 years ago. I guess technology has moved on far enough to make a better, more cost effective product this time around?

    Man, that makes me feel old!

    Thats some great shots, I remember talking Wade Simmons into jumping off the Norco van while I sat on the bumper. The RAC was my project with Easton, unfortunately we had to invent every aspect of the manufacturing process back then. Thanks for putting those cool old photos up! Cheers, Bryson-DVO

    XC USD fork? Any XC bikers want this?

  • Snfoilhat

    Too bad about the years-long marketing effort across the industry's big players to distinguish 110x20 front ends as 'for AM/DH only' and the resultant legacy of high-end 100x15 front wheels and entrenched belief among their users that 15QR would always be 'good enough' for XC/trail/AM. It might be nice, for a would-be USD fork designer in 2014, to have more axle with which to work, even for shorter travel forks. But no one dares bring a product to market that will alienate a bunch of crabby old guys who want everything new to work with everything old. Oh well.

    I can already see that fork collecting dust on the shelves of mtb bike stores everywhere. Only ones that would sell will be at a 75% off clearance price.

    I think it's a hoax. I'll bet fifteen bit coins that this is actually just a new take on the floor pump with adjustable rebound and dampening.

    Id prefer a floor pump with damping
