Checked out the skewers.

That's a sweet build! I wish I could get down to a 145lbs so I could dream about riding a set of AX Lightness wheels.
Like the bike. Love the Sci Fi novel collection.

I would love to hear your thoughts on your wheels. I have the same wheels (w/ tune hubs) and really like them. I love this build, it looks amazing! The only thing I am not sold on is the enve stem as it looks a bit bulky on this build....

Ah, that. Just IMO the most beautiful bike. Not in any sense a weight weenie. It's a Zullo "Vintage" - I picked it up second hand, had it repainted by Zullo, then built it up with Athena 11 (because it's the only modern gruppo available in a shiny alloy finish), built some Nemesis on (modern) Record hubs with Sapim Race, a Chorus Ti post and Selle Italia Flite 1990 with Ti rails, the standard-issue Cinelli Giro d'Italia bars and A1 stem combo and a Ti bottle cage. The only jarring elements are the chainset - Athena carbon - and the Speedplay Ti pedals; I might change the chainset for a Centaur alloy one (because I'd like to stick with UltraTorque instead of PowerTorque); the pedals will have to stay. I am also restoring an Alan Record Carbonio, which will be built with period C-Record and some period drillium/Ti parts; that will be on toe-clips.
Here's a quick'n'dirty pic with more books:

Tell you tomorrow - haven't ridden them yet. Saturday is RP day, so S5 with CXR80s this morning.
Stem, bars and post will likely change at some point in the next year as I start to chase a sub-5kg build. Probably an AXL or Mcfk stem, Schmolke TLO bars (maybe a Berk combo) and a Berk combo for the post and saddle. That and some Streeters should get me down to about 5.1kg. Thereafter it's cages and other bits of fiddling/tuning. I could obviously drop 300g by changing the chainset, but I want to keep the power meter, and I think the PowerLT is the lightest option for a power crank for the Cervelo at the moment. Possibly a Red 22 crank with a Stages arm might be lighter, but you have to account for the step-down adapters for the BB, since the BB30 Red is too narrow.
THM m3 srm is the lightest option that'll fit a Cervelo at 450g sans Chainring and bolts.
