Very nice.Cranks look real decent. http://www.pinkbike.com/news/Race-Face-2012-Exclusive-First-Look.html
Absolutely.Do...want...carbon sixc dh cranks...
EXI interface is similar than proven and reliable ISIS. Crank removal for chainline adjustments is a lot easier than with X-type. X-type requires a lot more torqueAtlas crank
• EXI interface complete with self extracting puller cap
• Light weight removable granny ring
Ok, what's the new thing here? And what is the advantage of EXI over the old system?
I quess this will work with EXI cranks also: http://raceface.com/components/bottom-brackets/bottom-brackets/bb30-x-type-adapter/No pf30? Strange since most companys making any kind of pressfit for dh is doing pf30. Would have been nice on my demo.
Don't know anyone who had problems with the X-type interface, but ISIS cranks tend to develop play when you put em on and off too often. But I still ride my old (2004?) RF Northshore Isis cranks.EXI interface is similar than proven and reliable ISIS. Crank removal for chainline adjustments is a lot easier than with X-type. X-type requires a lot more torque
to get crank bottomed to spindle and to be removed. Thought I haven't had any problems with X-Type interface. Small bearings were the problem of old ISIS standard BBs, EXI interface cranks implements external bb cups specs, but as I mentioned ISIS like crank interface has been remained.
I have read that after many installations X-Type interface cranks have developed some play between crank and spindle. But that just internet talks.
I haven't noticed this.
Soon we have perfect crank&bb specs. External BB cups with large and durable bearings. Sweet ceramic bearings also available. Excellent crank to spindle interfaces. Spindles that doesn't snap. BB bearings are finally properly sealed on some applications. Strong and lightweight cranks.
Bygone are the days with crank&BB problems
The system is inherently flawed. Give it enough time w/ enough hard riding and slop will develop... I'm done w/ ISIS & raceface cranks in general.EXI interface is similar than proven and reliable ISIS.

Rode for years on mine without any either. Also, how is the interface much different in that degree than a SRAM crankset?9 years of hard riding on my various RF cranks and no slop and or play
Bicycle mechanics. You're doing it wrong.I have a set of RF dh cranks on my dj/bmx track bike and they have a crappy system of tightening the crank. They came with these soft plastic washers that are supposed to set the preload and tighten the crank arm. Basically in 5 rides the washers wear out and the drive side crank arm starts to get wobbley. At that point I started turning aluminum washers on my lathe to set the preload but the splines on the crank arm start wear out and it gets wobbley anyway. At this point I have a aluminum spacer that is at least 1/4" thick (they started with 1/16" plastic washer) and the cranks are getting wobbley again so I will have to make a thicker washer.
As I said, my Northshore cranks are still fine after seven years, but the ISIS interface is not sitting as tight as it used to. I can almost press them on by hand.RF Northshore DH ISIS cranks have lasted flawlessly on my use 9 years on one bike and other Northshore crankset on other bike 7 years. Only BBs had to be replaced time to time because of the blown bearings. Excellento.
Proper installation and maintenance are the key for long lifecycle of every product.

are they still making everything in canada? if so those sixc dh cranks will be mega-bucks.

But hey, seven years is a pretty decent lifetime for a biycycle part these days.
You obviously have never owned the xtype like I have. The crank arm is not a press fit, it is a slip fit. There is also no shoulder on the spindle. The crank arm bottoms out on the splines before it contacts the bearing. Therefore RF provides spacers that go inbetween the crank arm and the bearing. Over time the spacers degrade since they are a soft plastic and the crank arm starts to wobble(since the splines are a slip fit). This exacerbates the problem making the splines even looser. Then the outer most surface of the crank arm wears where the bolt and washer contact, then splined area of the crank arm gets thinner, therefore the need for thicker spacers. As I said, its a poor design.
making those spacers bigger is gonna make your problem worse.
But you know what they say make it idiot proof and they make a better idiot
Something must be out of tolerances because every x-type crankset I have installed have required alot of tightening torgue right from the beginning of the crank and spindle axle contact to get crank bottomed out to spindle splines.The crank arm is not a press fit, it is a slip fit. There is also no shoulder on the spindle.

they were advertised with a 600eur price tag here on eurobike...are they still making everything in canada? if so those sixc dh cranks will be mega-bucks.
$444 according to QBPAny1 remembers what was XO DH retails price, if announced?
I put play in my race face fixie cranks in 9 months. Not from taking them on and off either, I think it was from skidding. I was less than impressed with the interface quality9 years of hard riding on my various RF cranks and no slop and or play

No, I know how to install race face cranks, I've done it a thousand times on a thousand different bikes. Plastic spindle spacers are not what's up at all. I've got XT cranks on the fixie now and couldn't be happier (even got the chain-line with in .1MM)obviously user error
