I went ahead with my 'Test Lace' pattern which I think I mentioned a few weeks back. A combo of Sapim Race and Laser. Being disk wheels, a different mix of 14/15 and 14/17s then I have done before.

32 spoke 3 cross on NOS XTR centerlock hubs. Pacenti's newest disc rims. 25mm H x 24mm wide.

Rear drive side trailing and disc side leading 14/15 Race with brass nips. The rest alloy nips and Lasers. Front will be all Lasers and alloy nips except the leading disc side which will be brass nips and 14/15 Race spokes.

Rear is over 1/2 lb lighter than the XT rear on the set I built [see front in pic] a few months ago. And the XTR has steel disk locking ring and 12-30 Ultegra cassette VS the Dura Ace cassette on the XT set.

Rear wheel done, working on the front after I eat. ;)

I should mention some tire girth points I guess.

On the SL25 rims, the 25C Pave CG initial girth is 26.5mm W x 24mm H, I expect it to swell to a little. The older 27mm Paves on same width rim is 28mm Wx26mm H.

Walter, I have not been shy doing some gravel shortcuts near my house with the 27mm Paves. Quite surprised how well they handle these chucked up gravel filled crater ridden back roads. I of course don't plow through the unfilled craters. But I was not thinking gravel bike when I got the Roubaix.

Really surprised the 27mm tire are big enough for that sort of thing. And a lot better than when I took my 28C All Seasons on same shit. Which did cut up the sidewalls unfortunately, but they are pretty worn these days. But still not flatted with those Contis AllSeas I should say as I digress...

We're the tires a tight fit on the Pacenti rims?

"We're the tires a tight fit on the Pacenti rims"

Below, I just copy/pasted from a post I entered in RBR re tires and the SL25s out of laziness to answer your question ;(.


______
Used double layer of the blue Pacenti supplied with the SL25s.

Now I did not mount a tubeless, but tried a few clinchers, and last left on a new 25C Vitt Open Pave CG. I mounted a used 28C GP All Season, one of the Spesh 25C that came off my SL4 Roubaix the same day I picked it up, and a new 25C GP4Ks Chili.

All mostly mounted very easily by hand. But I got gorilla mitts, so that may not apply to all hands. The Open Pave the most difficult, but not bad at all. And I find open Vitts of the more PITA ilk on initial new mount until they swell up a little. The 27mm I have also a bit of a fight, more so maybe, but different rims too.

The Paves about as tight on the SL25s as the Hutch tubeless 23s on my old 780# Scandium tubeless Dura Ace wheels mounting wise I would say.

On the SL25 the 25C Pave CG initial girth is 26.5mm W x 24mm H, I expect it to swell to a little. The older 27mm Pave on same width rim is 28mm Wx26mm H. I think I may do 25/27 front/rear with these being I have 5 of them [3x27mm 2x 25mm]. I thought the 25 VS 27 Pave would be more of a diff.
---------------

Just remeasured, the 25C Paves did not grow much. Like 26.6mm to 26.8mm mounted. I seem to recall the 27s grew over 1mm. And the 25s got 10lb more air put in them FWIW. I wonder if that is more about bead creep than tire swell. The 27s got put on non tubeless rims.

Got a ride with these earlier. I went to use them the other day and the NOS hub had sticking pawls and it took some disassembling to remedy that.

But the bike totally lost any of the truck feel with the MTB rims/XT set with the 27s Paves. I did a few hill repeats locally and definitely feel the lighter weight going up. Like a snappy light wheelset. I may be onto something with this spoke pattern/ga mix. My take on using Lasers for a disc wheel build, which Sapim says not to do... I will do it again on the XT / 650B set I am building..
