    Nope, not unless there's a new CK version that can mount where a Campy 42mm Integrated Headset would mount. The 44mm King Internal headset won't fit.

    Allow me to clarify:

    Campy = INTEGRATED. No cups pressed into frame, bearings drop in directly.
    CK = INTERNAL. Cups press into frame, bearings go into cups.

    CK does not work with any of our carbon frames. It works on our Vertex 30 / 50 2010, and in a roundabout way w. our 29'ers. (mix+match w. 1.5 lower)

    thanks for the info!

    so i presume the fsa headset that came with the frame is the best you can get for a vertex rsl 70?

    RMB-PM,

    Mind if I ask a question? Is there any reason for going integrated on all alloy/CF framesets?

    1. Lighter system weight
    2. Oversized HT = stronger = lighter
    3. Better bearing separation
    4. Easier service (no special tools required)

    Are the 4 main reasons...

    Ohh wait, I just can't do that! I'm holding on to my "older" RM's more than ever now. The only exception is this year's Blizz, but that's an other story.

    Sorry, but none of those reasons are true.

    1. The weight advantage is miniscule.

    2. The head tube is not strengthened by removing the bearing cup. If anything, by having the bearing placed directly against the frame, you are applying more forces onto the frame and harming the frame directly. Furthermore, the bearing cup (which is almost always a stronger piece of metal than the frame itself) absorbs the loads from the fork against the bearing, and distributes them unto the headtube over a wider surface area...thus protecting the headtube from damage in two ways, actually.

    3. Better bearing separation? What does that even mean?

    4. Easier service? A bearing cup remover is $30 or $40. But you don't even need to remove the cups to service the bearings.

    1. Miniscule? So in fact it is true? FYI: here are 2 equivalent headsets...

    FSA Orbit C Integrated - 73g
    FSA Orbit X Trad - 95g

    Sounds stupid, but it's not all that easy to eek 22g out of a frame. Our engineers also swear they can make the headtube lighter, since there is no pressfit to hold the cups in place. Extra material is needed to resist that pressfit. So the SYSTEM weight (headset + frame) is indeed lighter...

    2. I didn't say anything about the headset interface being stronger... the whole font end is stronger, since there is a larger area to work with, to move carbon around. The OD is bigger, without adding thickness...

    3. For the same given stack height (on the bike, incl the headtube), the contact points with the frame are further apart. I.e. where the integrated bearings sit in the frame (where the loads are) is further apart than the traditional contact points of cups (where the loads are). The further apart you can get the loading points, the more solid the connection. And again, for the same given stack weight, the headtube length is longer (by about the height of the 2 cups), and longer HT's are stronger. And if something is stronger, it can be made lighter.

    4. To service bearings, no, you don't need a $30 - $40 tool, or a screwdriver and a hammer if you're REALLY thrifty. Nor do you need a $200 headset installer from Park tool. But if your headeset is dead / kaput / old / ugly and you feel you need to remove the cups or press some back in... Then you either buy the tool, pay to have someone else do it for you or if you're a bro, buy someone a beer. So yes, all things being equal (New headset to new headset), it is easier on maintenance...

    Look, I know there are a lot of integrated headsets haters out there. And I know we can't make EVERYONE happy ALL the time. And I suspect that you, Waspinator, are a die hard traditional HS kinda guy, and that's cool, CK makes killer headsets (I own 2, but have fewer and fewer bikes to put them on). But there is a lot of misinformation out there on the subject.

    But on occasion, we do think some of this stuff through.

    Oh, and of all the 5.5" travel Altitude RSL's out there being over-ridden and abused... Not a single report of headsets troubles. Oh, and BMX have been using integrated (in steel, granted) for years now. If a 25lbs bmx falling from 8' onto it's fork doesn't kill an integrated headset, not sure we can on the Vertex RSL either.

    Sorry, no multi colored CK headsets here....

    Twenty-two grams is the weight of about nine pennies. Yes, I know that every gram adds up, but you're removing weight by removing a very important part from what is quite arguably the most important part of the bike.

    Our engineers also swear they can make the headtube lighter, since there is no pressfit to hold the cups in place. Extra material is needed to resist that pressfit. So the SYSTEM weight (headset + frame) is indeed lighter...
    Instead, you're using in your frame a design where you drop in a bearing that is not tightly held in place (i.e. there is far greater potential for movement of these bearings when forces are applied to the fork). And this bearing is being placed directly against the frame....which very well may be a $1000 or $2000 product! If the headset isn't perfectly tightened, any movement is going to result in the bearing rubbing directly against the frame. It's a bad design. Period.

    2. I didn't say anything about the headset interface being stronger... the whole font end is stronger, since there is a larger area to work with, to move carbon around. The OD is bigger, without adding thickness...

    3. For the same given stack height (on the bike, incl the headtube), the contact points with the frame are further apart.

    "For a given stack height". I'm sorry, but that argument doesn't hold water, especially since there is such a thing as an "internal" or "zero stack" headset (i.e. where the bearing cups are hidden within the headtube).

    As for your strength vs. stack height benefit, I don't have any statistics to comment on it. Although, I suspect that you're merely making a conjecture.

    4. To service bearings, no, you don't need a $30 - $40 tool, or a screwdriver and a hammer if you're REALLY thrifty. Nor do you need a $200 headset installer from Park tool.

    Pay someone to do it for you? I've never had a bike shop charge me more than $25 to remove an old headset and install a new one. But what if they charged $50 for the process? How often do you need to replace your headsets? I've ridden a Syncros headset for the last ten years, and it is still working flawlessly. In fact, it's the frames that have changed, and the headset has been removed and installed into two different frames.

    Look, I know there are a lot of integrated headsets haters out there. And I know we can't make EVERYONE happy ALL the time. And I suspect that you, Waspinator, are a die hard traditional HS kinda guy, and that's cool, CK makes killer headsets (I own 2, but have fewer and fewer bikes to put them on).

    Ummm, not really. Much of the design decisions of the biking industry are made based on fads. In contrast, you look at some of the highest-end manufacturers--i.e. Litespeed, Merlin, SevenCycles, Colnago, and so on -- and you'll see that most of them do not use integrated headsets. Not anymore, at least. They either use standard threadless headsets or zero-stack headsets. They make expensive frames, and they value the benefits of bearing cups.

    Oh, and of all the 5.5" travel Altitude RSL's out there being over-ridden and abused... Not a single report of headsets troubles. Oh, and BMX have been using integrated (in steel, granted) for years now. If a 25lbs bmx falling from 8' onto it's fork doesn't kill an integrated headset, not sure we can on the Vertex RSL either.

    "Not a single report of...."

    Did you ever consider the possibility that problems aren't getting reported to you? It seems as though you don't do business with online retailers, so customers probably take their problems to their local bike shops who are likely to handle them directly.

    Moreover, what kind of "troubles" did you have in mind? I'm not talking about someone cracking the headtube or "killing an integrated headset". I'm talking about damage that probably does occur to the inside of your headtubes from bearings sitting directly, and loosely, inside of them.

    Besides, someone above, in this very thread, reported a problem!

    Finally, I thought I should mention: I just purchased one of your Vertex frames. It's my first Rocky Mountain product....and my first bike that uses an integrated headset.

    The top tubes and downtubes on titanium and steel bikes aren't big enough to make it worthwhile to use really big diameter headtubes, on aluminium and carbon bikes, big diameter DT and TT tubes are needed which makes bigger weld areas or carbon tube blending necessary which pushes the head tube size up.

    There aren't any standard 45-50mm diameter steel or Ti headtubes that would fit internal headsets, and that's why those custom steel or Ti frame manufacturers still use press in 1-1/8" headsets.

    And of course as many people discover, you can ovalize the thin headtube on steel or Ti frames and that means an expensive bit of headtube replacement or remachining necessary.

    You'd have to put aluminium inserts into a carbon frame to press a headset into it, you wouldn't want to be pressing a 1-1/8" headset into a bare carbon headtube. I wouldn't anyway. I like the ease of just tossing the headset bearings into the cups in the frame on my Vertex RSL and Altitude 90 RSL, piece of cake to install or change, and so far every bit as stable and solid as any press-in headset.

    My only complaint about internal headsets is that there are about 20 different versions, and they don't make every style/model in all the quality ranges. If there were only 2-3 different versions, they could make them all in the same quality versions.

    Well, let's agree to disagree. I'm OK with that. Besides, you now know how to get ahold of myself, Peteypete and JPHcross, so if you run in to any trouble, don't hesitate.

    For a couple of years, Litespeed used integrated headsets on a few of their titanium frames. But that's beside the point.

    What you're talking about regarding tube diameters may or may not be true. They've been using pretty damn big-diameter tubes for a long time now. Moreover, the tube diameter has nothing to do with the decision to use integrated or standard headsets (i.e. headsets with bearing cups). I'd have absolutely no problem with frames that require zero-stack headsets. (Of course, when it comes to a DH or FR bike, I'd want something that could use a headset with a deep insertion....i.e. like the Chris King Steelset or the RaceFace Diabolus).

    There aren't any standard 45-50mm diameter steel or Ti headtubes that would fit internal headsets, and that's why those custom steel or Ti frame manufacturers still use press in 1-1/8" headsets.
    I think you're mistaking "internal" with "integrated". Internal headsets are very similar to standard headsets. They have bearing cups, but the bearing cups are completely hidden the headtube. Integrated headsets don't use any bearing cups. The bearings sit directly (and loosely) against the frame.

    And of course as many people discover, you can ovalize the thin headtube on steel or Ti frames and that means an expensive bit of headtube replacement or remachining necessary.
    That argument in favor of the current headset designs is really, really weak!

    First, it doesn't justify the omission of bearing cups.

    Second, it's very easy for manufacturers to beef-up the ends of their headtubes in order to prevent ovalization. GT did it for a while. They machined their head-tubes so that they had a little extra band of metal near the headtube faces. Ovalization problem solved.

    Third, ovalized headtubes aren't even caused by bearing cups specifically. They're caused by forces on the headtube. I have no doubt that a headtube can be ovalized by an integrated headset if the headtube isn't designed properly.

    And fourth: The potential problems with ovalized headtubes are can easily be remedied by designing the headtube properly (e.g. the GT headtubes I described above). But the problems inherent with having a bearing held directly and loosely against the headtube of a frame cannot be eliminated.

    You'd have to put aluminium inserts into a carbon frame to press a headset into it, you wouldn't want to be pressing a 1-1/8" headset into a bare carbon headtube.
    Carbon fiber frames have been around for a while, and they've been using standard headsets just fine!

    I like the ease of just tossing the headset bearings into the cups in the frame on my Vertex RSL and Altitude 90 RSL, piece of cake to install or change, and so far every bit as stable and solid as any press-in headset.
    Come on, pal. Seriously. How often do you need to "install or change" the bearings in your headset? Like I said earlier, I have a Syncros headset that I bought in 2000, and I've never had to change the bearings in it.

    And this convenience you're talking about comes at a price. The absence of a tight, positive seat means that you can have a bearing that moves around and rubs on the inside of your headtube....especially if the headset isn't optimally tightened. That just doesn't sit well with me. And it doesn't sit well with Chris King either! Nobody knows headsets like they do.

    My only complaint about internal headsets is that there are about 20 different versions, and they don't make every style/model in all the quality ranges. If there were only 2-3 different versions, they could make them all in the same quality versions.
    Yet another reason to completely do away with the ridiculous integrated designs. Actually, the internal (aka "zero stack") design can go too. Totally useless.

    Indeed. We can agree to disagree. As far as I'm concerned, this is just a friendly debate.

    I'm curious, though.....

    As for getting a hold of you, is it Rocky Mountain's expectation that anyone with a problem with their products join mtbr.com and contact you that way? Because there's no phone number on the Rocky Mountain website. Only an address!

    That's very odd, don't you think?

    Nah, we don't expect our main line of communication to be MTBR! It;s been said around here before, we rely on our dealers to interact with our customers. We don't want to cut them out of the loop. However, there have been instances where Peteypete has helped facilitate some issues.

    We weren't a very "open company" for the last little while, a bit hard to get ahold of... Consider our presence on MTBR a 1st step. We are re-working the website also...

    RMB, nobody wants the maker of their bike frame to be "a bit hard to get a hold of". Offering your customers a phone number to call and talk to someone is not difficult. You simply post the number on the website.

    The Vertex I recently bought looks like an awesome frame (integrated headset notwithstanding), but the lack of direct support is a bit unsettling.

    As for keeping bike shops out of the loop, let me offer you this opinion: there are a lot of us who steer clear of bike shops. Personally, I haven't had good experiences with them, so I handle all of my own bike building and maintenance. Other people have a problem with the price-gouging that is typical of bike shops. For others, bike shops are simply inconvenient. Have you considered the possibility that you should be offering your customers (and potential customers) an option with regard to purchasing your products?

    I could be wrong here, but I'd imagine that by only working through bike shops, you're severely limiting your customer pool. In the 17 years or so I've been mountainbiking, and having lived in five different cities since then, I have only encountered one bike shop that carries Rocky Mountain bikes.

    "Oh, and of all the 5.5" travel Altitude RSL's out there being over-ridden and abused... Not a single report of headsets troubles."

    I did have an issue with mine in that it was making a groaning/grinding/creaking sound when the handle bar was turned. I discovered when I took it apart for an inspection that both upper and lower surfaces were dry and covered in light surface corrosion. I wasn't sure if this was normal as I had no experience with this type of headset but I didn't think so. I ended up cleaning both surfaces and lightly greasing them. This appears to have solved the problem for now but I may have more reason to be concerned after reading this:

    Notice the date on that document. Also consider that if a company is in the business of making high quality headset cups, they might resist a trend going towards systems that don't use conventional cups.

    The sounds coming from your headset were fixed with a film of light grease.... those are noises that can come from a dry headset of any sort.

    This is the only point I have the energy to refute. Most headset bearings do not simply drop out of conventional headset cups. You need a bearing puller or a hammer and a screwdriver to get them out. A bearing cup remover is indeed only 30-40 bucks, but how much is a headset press? Sure a mallet and a piece of 2x4 works, but it's not pro or foolproof.

    As someone who avoids working on bikes like the plague (too many years lost in a bike shop) and who has to perform frame swaps regularly for team riders/ RMB staff, I do enjoy the simplicity bearings that drop into frames. As RMB-PM said, there have been no headset durability issues on Vertex RSL or Altitude RSL.

    Not really, Peteypete. When using headsets with bearing cups, I'd imagine that it's quite uncommon for there to be any play between the bearing cups and the headtube, especially since the bearing cups are press-fitted (tightly) into the headtubes AND supported by two surfaces (i.e. the inside surface of the headtube as well as the headtube's face). It would seem more reasonable that you might get noises between the bearing cup and the bearing.

    But you know what? At least you know it's just a cheap bearing cup and not your $2000 frame that's being damaged with every squeak and creak of your headset!

    As for your questioning Chris King's motives for writing that article, I think perhaps you're forgetting that Chris King--even at the time of the article--had other products that were highly sought-after. Moreover, if Chris King made an integrated headset, you can be sure that it would sell!

    As for getting a hold of you, is it Rocky Mountain's expectation that anyone with a problem with their products join mtbr.com and contact you that way? Because there's no phone number on the Rocky Mountain website. Only an address!

    That's very odd, don't you think?
    It's a tricky issue. I think you might be surprised at the massive volume of calls we receive from our dealers and if we took calls from individual customers, it would be crippling. This is why most bike companies do not sell, fill warranty claims, or provide tech support directly to customers.

    I hear you on being sour on some bike shops. Some are frustrating. We feel that for the most part our dealers perform a service that we simply can't one-on-one. Things like bike fit, helping with bike choice, service, troubleshooting, warranty, etc.

    For those customers that are completely knowledgeable and just want to bee-line it to the product they want, there are some mail order outlets that sell our products. It's important to know that customers like you and I are a tiny minority of bike buyers. Most customers need a bit of help along the way and will need help after their purchase. I bet most bike buyers aren't even comfortable using a barrel adjuster. We aren't a tiny company and we aren't a huge company, but we are big enough that we have to structure our business to meet the needs of as many of our customers as possible.

    That said, a Rocky Mountain contact email address on the website is coming. Stay tuned. It is way, way more complicated than you might guess to facilitate, but we're going to make it happen because we want to be as open as possible with our customers.

    As for your headset complaints, I want you to ride the hell out of your bike. If you have a headset issue, you can rant and rave to your heart's content... but why not cross that bridge when you come to it? You might be surprised on how well the system actually works. No headset is as durable as a Chris King threadless headset - we all know that- but give it a shot first before you assume the worst.

Sure a mallet and a piece of 2x4 works, but it's not pro or foolproof.

    As someone who avoids working on bikes like the plague (too many years lost in a bike shop) and who has to perform frame swaps regularly for team riders/ RMB staff, I do enjoy the simplicity bearings that drop into frames. As RMB-PM said, there have been no headset durability issues on Vertex RSL or Altitude RSL.

    Peteypete,
    Bearings can be serviced without removing them from the cup (and without removing the cup from the frame). Chris King calls their bearings "user serviceable" for a reason. But even if you have a headset whose bearings have rubber seals on them, you can still service them yourself.
    But let's be realistic here: how often do you need to "service" your headset bearings? Once a year at most? If you get the right kind of headset, you don't need to service the bearings at all! My Syncros headset (which I purchased back in 2000) is so well-protected from mud and dust that nothing gets to the bearings. They are perpetually clean! The only thing I do is apply some grease to them from time to time.
    The convenience of integrated headsets you're talking about is coming at a potentially huge price--i.e. damaging your frame. I flat-out don't believe your or RMB's claims that there "haven't been any problems". Two people in this thread have already reported problems. And again, I will re-iterate, that the design itself looks like a bad one.
    Any inconvenience caused by bearing cups is an exceedingly minor one. You are grossly exaggerating the difficulty they cause you! Furthermore, if you're swapping frames all the time, you are going to have all of the necessary tools to remove and install bearing cups. $200 for a headset press is a minor cost, especially since the tool lasts pretty-much forever!
    Finally, why don't you just find a reasonalbly-priced headset model and install one into each frame you plan on using, and leave it there. That way, you don't need to repeatedly remove and install them as you swap frames?

    Peteypete,
    The one bike shop I ever encountered that sold Rocky Mountain bikes had two models on their floor: an outdated Slayer, and the ETSX. No Switch. No Element. No Vertex. And definitely no RMX.
    I'd surmise that a solid majority of people who spend $2000 or more on a mountainbike are probably looking online for it. And I'd also imagine that the vast majority of people who are looking to buy a frame (i.e. just the frame) are looking online. I know that JensonUSA carries a lot of your bikes, but they don't sell any frames.
    ......which brings me to another point: There are a lot of people who just want the frame!
    It's purely by chance that I was browsing eBay for a Scott bike frame, and your Vertex RSL 70 frame came up. Had that chance event not taken place, I'd have been riding a Scott! It would be nice if you sold most of your frames alone, as well as part of complete bikes.

    Why do people keep insisting that the King is the be all end all of headsets?

    It's a poor design without the split compression ring to hold the steer concentric. The movement in the top cup would explain the wear shown on that top cap in the pdf linked above.

    PVD has a good explanation.

    Have you ever installed a King headset? The top race fits very tightly around the steerer. In most cases, it has to be hammered down onto the steerer tube. There is no play whatsoever--at least, none that you can recognize. The Cane Creek compression ring will produce only a slightly tighter fit. I cannot imagine that forces encountered during a ride would result in movement of the steerer tube when using a King headset.

    If there's one thing you can say about Chris King, it's that they design everything very carefully. If play between the steerer tube and the top race was a possibility, they'd have caught it.

    The other thing to remember is that King is aware that headtubes are not always perfectly faced, and that a headset needs to allow some room to accommodate this. It's quite possible that they specifically didn't want a compression ring, for this very reason.

    Finally, as for the patent, are you sure the compression ring is patented? Compression rings have been around for a looooooong time.

    Actually, my vote for best headset would go to the Syncros Hardcore (the original one. NOT the one they are making currently). Also, the Blackspire Shore headset is about as good. Neither of them use compression rings.

    Did you read the link I provided?

    Dia-Compe USA (now Cane Creek) made key developments in the threadless headset (AheadSet®) and holds the patent on the design using a split compression ring (U.S. Patent #5095770
    The King uses an o-ring to achieve that tight fit on the steer. I'll take a steel compression ring over a rubber o-ring to keep all parts in concentricity.

    I did indeed read the link. And I am aware of the rubber O-ring.

    My point is that the O-ring produces a fit that is tight enough, while simultaneously allowing some leeway with regard to fit (i.e. from improperly faced headtubes).

    Think of it this way: a headset is a fairly simple device. Designing a headset isn't like designing a computer! For a while, Chris King made nothing but headsets. They established themselves as a quality-driven company because of their headsets. Clearly, they designed their product very carefully. And clearly, everyone who has used a King headset in the past has had an excellent experience with it (including myself).

    If Chris King didn't use a compression ring in their headsets, you can be pretty darn confident that they evaluated their headset design and established with a high degree of confidence that a compression ring is not needed.

    I will make this additional point, though: Chris King is the only company out there whose designs are unconditionally trustworthy.

    God, I hope you don't have any opinions on direct mount front derailleurs Waspinator!

    Anyway, how you finding the frame? I'm considering selling my ancient FS at the moment, I hardly ride it since getting Vertex (although the new Element might replace it soon!)

    Unconditionally? Come on really? That's religious zealot talk.

    The enigneerds at Dia-Compe beat them to the punch and designed a better mouse-trap. They just forgot to make it in pretty colours.

    I agree that CK headsets are unconditionally trustworthy. Their rear hubs, not so much.

    Shirk,
    If you knew me, you'd know that I am the world's biggest skeptic. I've criticized frame designs using mono-seat-stays, I've criticized the use of disc brakes on bikes, and I've criticized riser bars. I now ride bikes with disc brakes and riser bars!

    Chris King makes awesome products. They always have. And once again, you simply cannot deny the impeccable track record of their headsets. Yeah, I trust King's designs unconditionally.

    Furthermore, are you aware that most headsets DO NOT use compression rings? Headsets without compression rings are a long-standing, tried-and-true design. The compression ring is clearly not necessary. I don't even think that there's any appreciable benefit to it.

    My Vertex frame is en-route. I haven't bought components and wheels for it yet.

    That track record went out the window when forks went over 120mm. As forks got longer people started riding more aggressive and it revealed the flaw in the o-ring design.

    If the King design is better why wouldn't everyone want to license it? Long list of licensees for the split ring design.

    The patent expires Sept 29th 2010, lets wait and see if King continues to use the o-ring after that.

    You DO realize that Chris King makes a headset intended to be used speifically with long-travel, DH and FR bikes, right? It's called the Steelset. And it doesn't use a compression ring either.

    You want me to go dig up all the threads on MTBR, Pinkbike, Ridemonkey, NSMB, and TGR with the people that are un-happy with the constantly loose King o-ring design headsets regardless of skirt length or material. It's not about the material of the cups or the length of the insertion into the headtube, it's about how things are held tight and concentric. The o-ring just doesn't do it well.

    I think I'll take the road of RMB-PM and say I guess we'll agree to disagree.

    I will add that I think the IS system that is being used on this Rocky that started the thread is better than ANY other system on the market. I've used it on steel and aluminum bikes and will soon use it on a carbon bike with zero issues.

    I hate to dig this therad up again but my FSA Orbit headset has died, it wasn;t the expesnive one with sealed bearings, looked more like a roadie version. Question is who does make headsets for this and what are the important numbers, as I understand it there are 2 chamfer angles/standards on integrated headsets?

    Cheers

    It needs to be the 42.0 mm Campy compatible version with 45/45 bearings. That's apparently also a popular BMX headset size (who knew).

    You'd have a more solid front end with the 42mm diameter headset, the 45deg bevel would keep the bearings centered but the outer edge of the bearings won't be supported with a 0.5mm space around the perimeter.
