Thanks so much for the response - Can't wait until I can get my hands on this
That's not the 3d+. it's the regular 3d, with the 24mm spindle. it's on an S3, it doesn't use the bbright system.
It works on any BSA frame. You just need to use the "BSA30" BB from Rotor. I am having a similar setup myself on a Storck frame with BSA BB.
Have not had a chance to ride them yet (I had to order BSA30 because my frame doesn't have BB30... in the future maybe and that's another reason I thought these'd be great). However, with the cranks, SRM meter, chainrings (53/39 standard, non-q rings) not including the BB, the weight comes in at 747g. BSA30 ceramic (according to comp. cyclist) weighs 88g so for me it will be 835g.
If I ever get the q-rings, it should drop some weight because I believe they are lighter than the standard non-q, but for now, 835 for a badass SRM, that is not carbon, is pretty .. well badass IMHO.
the kit doesn't come with any bearings from what I saw but maybe it's because I told him I'd be getting the BSA30 BB. It does come with spacers if you were using BB30. If I remember, I'll update once I get a chance to hammer on them.

My current setup is a cheap Shimano 105 Octalink, and the width of the crank at the axle is exactly 130mm, with a 145mm Q factor. Supposedly the Rotor 3D+ is 147mm, which is insignificantly different. However, it looks like the overall width at the axle is a lot larger, maybe 145mm or so based on pictures. Does anyone have a set of calipers that could tell me how wide it is at the axle? Is it wider there than with the old school Campy square taper SRM?

I have a set of standard Rotor BSA cranks, which the Rotor rep said have the same Q-Factor as the 3D+. I measure 147 mm from the outside of each crank arm face. There is 1 mm of inset on each arm where the pedal spindle rests against the crank arm. This brings the Q down 2 mm total, so the final Q is 145 mm.
Just so you know, this was measured several times with calipers.
