The first wheel took about 4 hours of work (at least), plus an additional hour after I took it to the bike shop and discovered the spokes weren't tensioned high enough.

The second wheel took just under two hours from start to finish, and all the spokes were tensioned right the first time.

I'll put about 50 miles or so on them, then true them a second time, have the tension checked and, if all is good, put thread locker on the spoke threads and be all done.

Full Specs:

Rims: SunRingle Assault 700c
Hubs: All-City Track Hubs, 100mm front, 120mm fixed/free rear
Nipples: DT Swiss Alloy, 2.0x12mm
Spokes: DT Swiss Revolution, 294mm (f), 293mm (r)

Completed weight without rim strip: 833g (front), 853g (rear). The EighthInch Tessa wheels (w/ rim strip) were 1237g (f) and 1305g (r), for a total weight savings of 1.8lbs.

Kasy went camping Saturday night at some grounds about 10 miles from Valley Forge. His rear wheel rim cracked on the ride up. On Sunday morning I woke up early, grabbed my rear wheel from my touring bike, strapped it to my messenger bag, and rode to Valley Forge to meet him so he didn't have to ride back on a bad wheel.

It was an awesome ride (~45miles round trip) and I'm really happy I had the chance to do it.
