Rohloff build into 26 inch Rigida Andra 30

Hello wheelbuilders. I'm a novice builder and would like some clarification regarding the titled build. I'm unsure about the comparison between European and French rim drilling patterns versus Type 1 and 2 patterns. Will someone please tell me which correlates with which please? Thank you folks.

Where are you seeing these references? I can't find anything about "European", "French", "Type 1", or "Type 2" rim drilling.

The European vs. French drilling is mentioned in the Rohloff owner's manual pages 121 and 122. Type 1 & 2 are noted in Roger Musson's Professional Guide to Wheel Building (5th edition) pages 9 & 10.

Imagine you are seated with the rim on your lap and the valve hole away from you (at your knees). When looking at the spoke hole on the left, it will be toward the upper (Type 1) or lower (Type 2) edge of the rim.

The Rigida Andra I bought from the UK has the holes centrally placed and I'm not 100% which holes go which direction. Musson's guide suggests dropping in a spoke, attaching a nipple and observing which lateral direction the spoke more naturally moves. Meaning it will move further in one direction than the other.

I'm in touch with the seller of the rim and they seem eager to help. I just figured a few of the BF members could offer some experienced insight.

Thanks for the reply joejack. btw, I still have the powergrips you sold to me a while ago.

It's all about the key spoke , the drillings are angled in the rim.
if over your head hire the job out.

Ok, that makes sense about the Type 1 vs. Type 2 drillings. I had a feeling that was what was meant. I would think that for a rim with centrally drilled holes that the holes would not be angled. I could also be quite wrong. The only rim I've built that had centrally drilled holes was an IRD Cadence rim and unless I completely missed it, they were drilled straight through. The small angle the spoke makes with the rim is dealt with by the head of the nipple which is rounded to allow for an angular exit. Even an angled hole can never be perfect as radial and cross spoking patterns all give different entry angles.

Thanks for taking those Powergrips off my hands. I never managed to get along with them and my one set now sits in my spare parts bin.

The issue with the Rohloff is that the flange diameter is 100mm which creates a more acute angle at the rim. That's why I bought the Andra and I'm suprised the drill angle isn't more easily detected. Anyhow, the seller ok'd my lacing from the photos I sent. Still need to true and tension. Might have a pro look at it and hopefully one who's built a few Rohloffs.

The build is 2 cross max , as specified by Rohloff. that resolves the large wide flange issue adequately.
The '04 Koga Miyata WTR I bought (26")
came laced 3 cross, more like 4 cross in a 36 spoke wheel , they started in the wrong hole .
so It didn't come out like in the catalog pictures, and so, though 3rd owner,
they sent me a new set of shorter Spokes from NL, and I re-laced it 2 cross .

my bike Friday Pocket Llama has a Rohloff in it's 406 20" wheel
that is made up with a 1 cross pattern , also in keeping with the manufacturer specs.

When you relaced with 2 cross, did you create new spoke indentations in the flange holes? I've been strongly cautioned to avoid this by a respected Rohloff user. I did hear a new shell can be purchased if the flanges fail. Price unknown.
