Right, well I finished the build last week, and raced the wheel on the weekend.
First impressions... Fast!!! This, combined with the Tune/CX-Ray/FarSports build I did on the rear, was genuinely shocking to ride for the first 5km. Way, WAY faster rolling than the heavy Mavic Cosmic Carbone SR I train on.
The race was cut short due to horrific weather, and despite getting a soaking, the ceramic hubs in the Extralite hub seem to be spinning fine. I had a look inside, and they are clean with the grease still in there, so that is good. Will not make a habit of riding them in the rain though!
So yeah, building it was easy once I figured out taking it apart, and putting it back together. Adjusting the bearing load was simple too, once I got the compression ring moving - that caned my fingers pretty bad.
The wheel comes in at around 360g, which is insanely light.
Tensioning was fine; did it up to average 90kg, with not much deviation.
It really is an excellent, high end hub, and rides like a laser on ice. Definitely recommend this to anyone thinking about getting a sexy, extremely light bit of Italian fanciness.
All good, and thanks everyone for the great help!
Next build, I am thinking about getting the matching Extralite rear...
