23.5mm internal asymmetric rim, double butted spokes, choice of brass nipples or alloy to shave some more grams, and really good quality hubs. Hubs are 11 speed, convertible, easy maintenance, super reliable. Hubs use made in Japan TPI bearings, same as DT Swiss.
This pair I shipped out early December.
Those are my wheels. Running great! Oleritter was so easy to work with and had patience with my endless emails regarding details as the build came together. Highly recommended!
