Rebuilt the Rear Wheel on an ENVE 2.2

Another day, another wheel (and so on).

A customer brought in an ENVE 2.2 wheelset for service. We'll check the front wheel another day, but they want the rear wheel rebuilt.

The rim is shifted to the left. The spokes are tensioned well, so I can't tighten them much more than they already are.

The customer's requests are three things: no spoke ties, tension it as tight as possible, and change from reverse Italian to Italian lacing.

I carefully loosened 16 nipples clockwise, exposed the 8 untouched nipples from the rim to see the spoke lengths.

There's some variation, but the non-drive side spokes are on the longer side. If I swap the drive-side spokes for heavier-gauge ones and incorporate asymmetric lacing, the non-drive side spokes I'm reusing will need to be tightened more than they currently are, so I'll need to shorten them a bit.

Disassembled the wheel.

I've mentioned this a few times before: with tangent lacing, there's a difference in spoke-head deformation between inpoke and outpoke.

↑ Inpoke deformation pattern
I want the original inpokes to stay inpoke after rebuilding, and the original outpokes to stay outpoke, so

DSC00506amx12.jpg
I removed only the outpokes first.

Shortened the original outpoke spokes slightly,

DSC00509amx12.jpg
and swapped them with the original inpokes.

DSC00510amx12.jpg
I shortened the original inpoke spokes,

DSC00511amx12.jpg
and threaded them in as inpokes here. This way I've converted from reverse Italian to Italian lacing while reusing the inpokes and outpokes in their original configurations.

Built it up.

Of course, the wheel is centered.

Originally it was a 4-cross lacing pattern, but

DSC00520amx12.jpg
even if I changed it to a 6-cross pattern, the flange is so extremely sparse/dense that the wheel's characteristics wouldn't change much. And sourcing slightly longer (i.e., new) spokes just for this didn't seem worth it, so I kept the lacing pattern the same.

Oh right, since I completely disassembled this wheel, it technically meets the criteria of "another day, another wheel" (and so on), but that's beside the point. Because there was a moment when the rim sat by itself, I obviously had to weigh it. But I'm not telling you!
