According to Jim from Quarq, there will finally be a 110 mm spider available, for the Lightning crankset in 6-8 weeks: they're just waiting for production, there's no more development to be done.
I have a Lightning and I really like it. The bearings have an adjustable pre-load, and spin quite nicely, even with steel bearings. A Striking contrast to GPX or Shimano, where the unloaded crank arms barely spin: with Lightning with the chain connected, I can easily backspin the crank arms 3 full revolutions, similar to the old Octalink Shimano bottom bracket. So perhaps losses in the bottom bracket are less.
The crank is also extremely light: Vuma Quad light with SRAM chainrings. Lighter if you are willing to go to Extra-light (which I won't do because I want a 36, and Extralight only comes in pairs with a 34). The Vuma isn't an option for me since it only comes with a 34.
I wonder if they'll be a Specialized 110mm solution soon, as well. I suspect so, as the Specialized and Lightning are similar.
Quarq is taking awhile to come around on 110 mm.... I wonder how far Brim Brothers is from production? Obviously a sensor in the cleat is an attractive alternative to the crank, for a variety of reasons. Hard to say, but no indication very soon.
One thing I'd like to see from Quarq is a lightweight, low-cost, ANT+ Sport data unit. It doesn't even need to display power. Just a USB stick I can jam in my jersey pocket, then download data after the ride would be nice. Minimal weight, minimal fuss, maybe $200 and they earn a tidy profit on the thing not counting amortized development cost. Indeed, Jim has hinted on working on such a thing in his interview with VeloCity.
