I thought machine-built wheels did not build to the same pattern as hand-built. Something about how the machine works. On modern hubs I think it's sort of okay (obvs not ideal) to ignore the indents. Again depends on abuse/ flange thickness/ whatever.

For matching deformation on a used hub, I like to figure out which hole had the key spoke in it, use it for the key spoke again and go from there.

8 non-driveside trailing spokes

got an rr460db rim for christmas, so just ordered all z pieces for a rebuild of this white industries front. man dt swiss makes it easy! they put the ERD right on the rim. hopefully this stuff shows up before the weekend.

Machine-built wheels can be built to any normal pattern.

There’s a chance that the rims had different hole side nearest valve hole to change it up? That would change your lacing pattern.

I measured the Alex Adventurer 2 rims that I'm going to build for my Schwinn and for the first time in my whole history of wheel building, the published ERD was exactly the same as my measurement down to the millimeter.

if you lace using the gerd schraner method from art of wheelbuilding, you can pretty easily change which direction you put the spokes through, to match the hub scars

Thanks for the feedback/suggestions.
Took some photos last night after setting up the truing stand and getting tools ready.
Turns out all of my 3 relacing errors got jumbled in my brain.
The issue is that one flange matches the scars while the other seems to be one hole off.
In the process of trying to get one side to line up I laced the wheel opposite (key to right of valve) of what my two books suggest (key to left of valve). Not sure if that matters as long as you continue to mirror the lacing in the instructions.

This side looks good:

This one, not so much:

But wheel looks normal to me:

Thanks

i would just relace the one side of the wheel that is wrong. it'll be a small pain in the ass to wiggle the spokes through but it should work fine.

I always lace key to the right of the valve per Sheldon.

Because you reversed the key spoke, you have attached spokes to the rim in a "backwards" way. If your rim is directionally-drilled, it's probable you have introduced more stress at the spoke-nipple interface. If your rim is center-drilled or directionally-drilled in the uncommon way (old rims, some French, some Dutch, etc), then no problem.

Here is what you need to do conceptually although it will be easier to take it completely apart. First clock the rim so your taped spoke is one position further from the valve hole. Then you will have fixed the "backwards" problem but created a non-parallel problem under the valve hole. Clock the spokes on the NPS (non-power side) by one position, both at the hub and the rim (leaving the PS spokes in place). Then you will have fixed the non-parallel problem and lined up the scars. You can confirm or disprove this theory before doing anything by verifying the lesser scars on the flange insides will line up as well.

Squirrel, you are in a little zone of variation that I like to use to get hub labels lined up. Making the key spoke ds or nds can get that one detail perfect, but it can also fuck up either rim handedness or in your case, spoke indentations. And Sheldon says to only do ds keys.

But yeah tldr, my intuition is that your key spoke is on the wrong side and currently is pointing the wrong way. Do you see your current key spoke? Have a look at the one coming into the rim into the very next hole down from the valve. It is a spoke running parallel to the key but from the opposite hub flange. This is now called the key spoke's buddy,, and it is the role that your current key spoke needs to be in. So it is one spoke hole away from where it needs to go. And so the whole wheel needs to be redone, both sides.

Warning : this is off the top of my head and may be insane

Guys, I built a set of those Alex Adventurer rims the other day and can confirm that they are super fucking awesome. So round so true.

Same here. Built some in 700 and 26 now. Best in class.

Woo, Finally got the wheels relaced and everything is perfect except for the label alignment.

I also made a terrible discovery after initially fixing everything. Upon closer inspection the Pacenti Brevet rims have a very subtle alternate drilling unlike the Pacenti PL23. Dammit! Had to completely relace again & take that into consideration. Wish they had put some arrow stickers on rim bed to tip off the builder like Light Bicycle does with their rims.

I can't complain though, I learned all the hard lessons on this build but feel like I can deal with all the lacing considerations on the next wheelset.
Thanks for feedback.

What an epic that wheel build has been!
Congrats on getting it all set.

Nicely done mr squirrel. These painful lessons build expertise.

Does anyone have any idea if/when Alex will be selling their rim-brake 650b Adventure 2?

Finally had a second to setup tubeless Extralight Babbyshoe on the Brevet rims.
Couldn't do it with normal pump strokes but once I engaged the tubless pump dump tank the tire bead jumped on the shoulder without much trouble.
I put 3 passes of tubeless tape on the front (finish a roll) and 2 passes on the rear. Front wheel tape seemed to help get a slightly better seal during inflation.
Had to do some slight retensioning on the front wheel after mounting and inflating the tubes.

Photo album here: https://www.flickr.com/photos/andy_squirrel/albums/72157668510146559

Click for video:

Old Wheelset with PL23 rims, straight gauge spokes, worn EL babyshoe pass tires, tubes... etc
Front: 1583g
Rear: 1664g

New Wheelset with Brevet rims, double butted spokes, brass nipples, new EL babyshoe pass TC tires, sealant, valve stem, tape, skewers, cassette
Front: 1520g
Rear: 1640g

Other interesting measurements.
PL23 Rim inner width: 18mm
Brevet Rim inner width: 19mm

TC Extralight Babyshoe weight: 374g (both identical)

Initial inflation (not stretched) TC Extralight Babyshoe width = 39.5mm
Interested to see how much it stretches out since Compass claims actual 42mm width.

Nice work!

If someone on here did it, I'd probably like it. Since it was done by someone I don't know, they're a fucking idiot.
