Confirming Direction of The RM29C19 Light Bicycle Carbon Rim

The RM29C19 Rim Indeed has a +-5 degree angle for each spoke, and I think I have the direction right. 

See the "direction" arrow below near the first spoke of the wheel near the valve hole.





And here is the broken end of the spoke:


2 Spokes in 2 Days - breaking Sapim spokes at the threads?

 Needed a place for photos on this one so I thoughts I would post here.

Prepping the bike to ride last night late, I found a spoke hole staring back at me and noticed something rattling around in the rim.

Removed the tire, then rotor, then the cassette, cleaned up with Stans, and the let out the metal - not only the nipple but the chunk of the threads.

Found the spare spokes, used as new nipple, marked the spoke with tape, trued (though it was not out much) and tensioned the new spoke, duct taped the rim, then tire, some air, cassette and rotor back on.

Got it all back together, pumped it to 50lbs, went to bed woke up and rode WMD with the gang.

I scrubbed some air out along the way, everything working fine. We decided on the final leg and I did hear some rattling, I assumed it was my noisy hub or derailleur (each with their own issues and recent maintenance). 

Back home, bike on the stand and I spin the wheel, here noise inside the rim and find another hole staring back at me. It was not the taped spoke, so its a new thing. Took some pictures, and here we are.





Data on what I ordered July 19, 2020:


I reached out to WheelBuilder tech support to see if there is anything I should do before tearing off the tire and duct tape again.
