Mountain Biking - New kind of BB.

Thats the new bottom brackets that RF will introduce, the question still remains as if they are still ISIS compatible.

Oh-oh... I think my wife is running to hide the credit cards and checkbook. :D

Damn, that thing looks like it can take punishment.

It really looks like business to me,,,,,reliable etc etc, even if its not released and tested yet, but i would be VERY dissapointed if i find out that its a new proprietary system.

and very sexy too :D

Oh Look it's a Shimano M960 XTR clone!!!!!
Oh it's a Race Face

How is it an XTR clone? The left crankarm doesn't attach to the spindles via pinchclamps and the right one (I don't think) isn't permanently attached to the spindle like with the Shimano integrated BB. It is basically a refined and beefed up splined interface with bearings placed outside the BB shell.

MOREEE NEWSSSSS. Raceface TurbinesLP, and NorthShore Series of cranks are going to be DISCONTINUED. The new RF 2004 cranks to replace them ARE:

DeusXC available in ISIS and the new X-type spline with external bearings (Turbine replacement)
Athlus in ISIS or X-type (model for allmountain trailriding befier than turbines lighter than NS)
Diabolus ISIS or Xtype! Replacement for NS cranks
EvolveXC/DH replacement for Prodigy XC/DH ISIS only

Obviously Turbines and NorthShores are out of the game....since they are discontinued....(damn and i wanted a turbine :D). Release date: Feb/March 2004.

I wonder if I can find a set of turbines for dirt cheap now that they are "obsolete"? I love that crankset.

it's an XTR clone fromt ehpoint of view that the ono drive side crank arm IS permanantly attached to the axle and the drive is'nt.
The bearings are outboard as well.

So an XTr rip off and they've got round the XTR patent by attaching the non drive siade to the axle.

Imitation is the sincerest form of flattery

The crankarms ARE NOT attached to the bb axle. so no relation to XTR

Talking about crank arms, those crank arms in that picture look downright strange. What is up with that kink in them?

Race face is making a very bad decision by discontinuing the two most popular crank sets they have ever made in their history. I'm thinking of getting a shimano Saint Crankset. Tried one today, very strong.

Danka the curve on the arms is for clearing the chainstays. The arms are not welded to the bb. New Xtype bb will be stronger and more longlasting that the RF signature series , more importantly it is expected to be 10% cheaper. Obviously if RF introduces Xtype splines....it would be hard to redesign NS and turbines again....so RF replaced them with Diabolus and Deus respectively. More important...the new Athlus (iirc) model sits in the middle of Deus and Diabolus in terms of weight and strenght!!!! Sounds like the perfect choice for trailriding.

So let me get this straight.
the only components locating the bb axle are the cranks bolts??
Seems like a lot of phaff for a gain in stiffness....
I'm not convinced that one of those arms are not permanently fixed....

Yeah right....only XTR is stiff.:fun:

no that snot my point so don't try and deflect this.

I'm bringing the unique ness of the neew RVC cranks and BB into question not the stiffness. learly outboard bearings is the way to go but that RF set up looks suspiciously similar to a XTR set up to clai it is completely different.
Do you have evidence to back up your claim that one of the cranks arms isnot permamnently joined to the Axle.??

I smell a Shimano patent infringement.

Well shimano is wellknown for using other's ideas and then she patents them herself and sues other for using them. The cranks have bolts on both ends on RF new line. It is irrational to bolt a glued crankarm to an axle. Attaching a crankarm to an axle is not a patent nor outboard bearings. I never said that RF was unique or blah blah blah....i just said its a radically new design in comparison with ISIS and square taper, and by the way i didnt mention XTR style or octalink simply because they are letter designs :D

and I merely inquired as to the exact nature of the fixing of the crank arms to the bb axle. It would seema great waste of effort of have those spacers in place if one of the arms was not fixed to the axle.
That was not an accusation but merely a confirmation that the XTR concept is a good one and that others ie Raceface, are going to follow the concept.

No need toget all defensive over your precious Race face product.

Look mate, i dont own raceface or shimano, and i dont work for either, i own parts from both brands and i am more than happy with both brand's products. The thing is that shimano hasnt produced anything new with XTR. PERIOD! RF doesnt use spacers , those blue thingies are bearing carriers.....

Jesus....this is not www.shimanoforums.net for supporters of XTR neither racefaceforums.net to support RF.

I bet you love www.xtr.com :P

theBB has three spacers in it Math!
the black rings are the spacers.
and there are 3.
two drive side and one non drive side aka xtr with 68mm shell.

Now clearly you have no idea if either crank arm is permanently fixed to the BB axle so I'm going to enquire from RF whether or not this is the case.

adieu

Sooo sweet. The new RF cranks look great too...<drool>

Hey guys, remember "BULLSEYE" cranks?

Yep, they're outboard bearing with drive side attached, made in the early '80's. Almost exactly what the Shimano XTR design is based on.

"I wonder who's the copyee and the copier?" http://www.bikepro.com/products/cranks/bullseye.html

oh, no secret.
Bullseye was first then shimano waited for their patent to run out and made their own version.
excellent idea.

quite innovative indeed...

There are lots of cranks that have one arm perminatly fixed to the bb.
It's still a fairly comon thing today with bmx cranks.

Also I really doubt there has been a patent in recent history on this type of crank.
1/2/3 piece cranks have been around for a long time so there would be too much prior art. Also once a patent has expired thats it, another company can't come along and re-patent it.

There just isn't enough room for an isis spindle and a decent bearing in a euro bb. OTher than making the bbshell bigger how else do you use a bigger bearing without moving it to the outside of the shell?

I wonder if some moron has come up with the silly idea of integrating the BB bearings into the shell ala integrated headsets yet.

You mean like Cannondales Hollowgram BB and Chainset.
Works very well.
Bearings are cartridge type and easily replaced.
Very well sealed to, not just the bearings.
