The ones released THIS year BEFORE the CX stuff had even been mentioned were POWER TORQUE! WHY IS THAT SO HARD FOR YOU TO UNDERSTAND????? Were not talking previous years apples to oranges. Power Torque cranks had been out almost a year before the CX PT was on the market and for the fifth time, THEY DON'T WORK TOGETHER MISS. Now go cook your life partner some breakfast and then apologize to me.

The previous centaur and athena cranskets were ULTRA torque Miss Jeff.<br />
<br />
ULTRA does not equal POWER in the campy range.

So the Athena and Centaur cranksets that were released <i><b>previously</b></i> <b>are</b> compatible with the CX <b><u>Power Torque</u></b> bottom bracket????<br />
I think not sir. I <b>never</b> said anything about joint strength. I was talking about how some cranks with splined interfaces use the taper as the number one factor of holding the crank-arm on. The crank-bolt is basically there for looks and in the slight chance the crank-arm starts to loosen off the spline. I like this Campy system…

The crank-bolt is basically there for looks and in the slight chance the crank-arm starts to loosen off the spline. I like this Campy system better as it appears as if the bolt is as much of a factor of holding on the spindle as the splines are which make removal a snap, but it also makes the bolt tension and thread-lock if it calls for integral as well.<br />

Because PT <u>is</u> new for 2011 and there is no 'previous' power-torque!<br />
<br />
It has 'hardly any taper' like ISIS drive 'has hardly any taper'. They're both splined tapers and won't fall off on their own.<br />
<br />
We can discuss taper angles and machine tapers if you like, but the taper angle is not the sole determinant of 'joint' strength, Jeff.

I don't understand that comment. I own UT cranks which I pictured, so how could I have them confused?<br />
As easy as that crank-arm slid off in that video there must not be hardly any taper on that spline. Normally the crank-arm almost becomes fused to the spindle and are ridiculously hard to remove.

I think you have got Power-Torque and Ultra-Torque mixed up.<br />

The 'no special tool' in the instruction sheet is a standard gear puller and a bit of rag. The crank has a sort of 'flange' which the puller can pull against. Plus use one of the ISIS crank plugs (that some square taper crank removers come with) for it to push against.<br />
<br />
The taper is fairly mild but not something you could hammer off I don't reckon (I'm not trying that anyway)<br />

<br />
Both 14mm driver and a gear puller are standard generic tools that any tool shop sells. Unlike, say a BB socket tool, or $200 chain tool etc that only a bike shop sells.... I know where I'd prefer to buy tools from, because without bicycle branding I know what's cheaper for the same quality!<br />

I couldn't see any difference between the PT Centaur or PT CX BB cups and enclosed bearings, other than the CX version had white seals which had more flexible, and double lip seals. I reckon they are interchangeable. Don't confuse these with Ultra-Torque of course! Not compatible (you'd be missing a bearing for a start!)

I'm still interested in the removal method on these. Campy makes special note in their last monthly newsletter that "no special tools required" for install and removal. By "special" do they mean something akin to a $200 chain tool or $165 for a tool to remove UT bearings? Everyone has a 14mm hex in their tool kit, right? Maybe the removal method will be a giant steel bolt with a large head and you'll just tap it with a hammer and knock the drive side arm through the bottom bracket just like a…

It's that 5th one that's offset so I would remeasure that if I were you. In the entire history of Campy they've been proprietary, the CX Power Torque bottom bracket isn't even compatible <i>with their other</i> Power Torque bottom bracket so why in the world would they start making regular 110bcd now? If they were normal 110 then that would mean you could buy off the shelf chainrings for them and it would defeat Campys entire purpose to release cranks with CX size rings.<br></br>

And why all the questions if these are or are not Campy 110 anyways? Are people planning on buying them and then immediately slapping some cheap 110 rings on there? Doesn't make sense. TA Specialties has <i>been</i> making the <i>highest quality</i> Campy CX rings for sometime now...<br />
