@Rigby - Ripping out your hair yet?
only because the hubs are taking forever to arrive!
Hellafaster...built
I like except for the shiny red tape. Reminds me of smeared lipstick.

Will be interested to hear some road test writes ups.

Sssshhhhh....Malcomson can hear you....
Stages Power Meter = Ordered through Ride Brooklyn.  There is no room for them to offer a deep discount for club members.  5% was all they could do...which means the meter is actually more expensive than ordering it online, due to sales tax and shipping....  I want to patronize a team sponsor though and if I have trouble with the meter, I have a shop on my side.  Now the waiting is the hardest part....don't know what the back order is but fortunately I ride Sram Rival and not many people that can afford a meter want to be seen with Rival on their bikes.  I don't care if it says "donkey spam"....as long as I'm getting consistent power #'s.
Did you get a new van Dessel as well?
We've discussed saddle selection before.  This is the most in-depth examination I've read online. It not only references assometers, but also discusses how you can make a home version.  And discusses the difficulty of figuring out a saddle for the tri' position.

Check it out.

Rags...you are way...WAY more fun when you're drinking...

Anyone have any experience with the fitbit?

I have experience with former (using), and the latter (giving).

Open ended questions aren't the easiest to answer.  I will tell you that the device seemed ok for walking, so-so for running, and pretty useless for the effort levels any one in this club is used to.  the sleep thing was ok.  Seemed like the biggest value was for sedentary people who needed just to walk around more--it coudl work well if they'd log their food.

The lashes I prefer to give on the bike.

meh.  consistent is the big question.  #youwontknowwhenyoudontknow
since we're on the topic of stages power meters. I have a SRAM Force crank on my road bike and FSA gossamer (I think) on the CX bike. Both are BB30. Could I buy either the stages FSA crank arm or the Cannondale hollowgram crank arm and put it on both bikes so long as I didn't mind the frankenbike look? (swapping the crankarm from one bike to the other)

 the Cannondale hollowgram crank arm and put it on both bikes
This is precisely what I am planning to do and I don't see why not. I will have to swap the whole crankset because you can't mix between one crank arm and another. This will also involve swapping the chain rings, which should be compatible as long as they are 110 BCD.

I'm going with power2max.
Why power2max?  Just curious.  Fantasizing about power meters.
DC Rainmaker seems to have the most thorough reviews these days

I read his Buying Guide last night but I guess I didn't see the power2max price.  http://www.dcrainmaker.com/2013/09/power-buyers-edition.html ... now I see why power2max
fascinating...

Loving mine so far.

Still love the Quarq too.

That is the essence of my question, why can't you mix crank arms if the BB format is the same? Are the spindles different such that a FSA BB30 crankarm won't fit on the BB30 spindle from a SRAM Force crank?
Craig, you nailed it. Spindles and arm attachment mechanisms are different between different brands.

Joaquin,
From preliminary investigations, it looks to me that at least SRAM and FSA use the Cannondale BB30 splines.  I just looked up images of splines for those cranks and BB30.  I haven't found a paper documenting it though.  The Specialized BB30 crank seems to use a Hirth joint like Campy.

The basic idea you're pretty correct about.  Shimano locked up lots of patents on their Octalink design and so the ISIS standard was created to be given away.  When Shimano went to thru-axle, they locked up some more patents.  FSA's attachment is different as is SRAMs as is Campy's.  

If they are the same, it's possible they are interchangeable, though they may have differend Q-factors.  I don't know if that's specified in the free standard.
Warning No formatter is installed for the format not-found
Did you try NOT RIDING OUTSIDE WHEN IT IS SO COLD OUT THAT SATAN IS THROWING SALT ON THE PARTS WHERE HELL FROZE OVER????

(just sayin')
the standard is only for the spacing of the bearings and spindle diameter.  looks like it doesn't specify how the cranks screw onto each other or long the spindle is. http://www.bb30standard.com/wp-content/uploads//2012/04/bb30standard_new.pdf

maybe i'll try to put an FSA crank from my gf's bike onto my SRAM S500 cranks tonight and let you folks know how it goes.
@Brendan - I for one would be very interested in your findings.
Take a look at the splines, measure the tooth profiles with a caliper, and place on, gently, by hand.  

This is also something someone should know.  I bet if you called FSA, they would tell you.  But that would be too easy.
Craig, I'll make the attempt sometime soon for your powermeter-buying edification.  But I doubt it will prove much because her bike has the entry-level FSA cranks and I bet yours are different.
