The Soma Eldon looks like it is the same rim as a Velo Orange PBP:
They both have a narrow 13mm internal width so only good for tyres up to about 28mm.
TB14s are 17.5mm internal and ADHNs are 20mm.
Velo orange also do Diagonale and Raid rims with a wider width but it looks like all 32 holes are out of stock.
Halo White line classics may be another option, but I think these are the same rim as the ADHN.
