I own and ride often DA7850 SL (with clinchers ... waiting for better tubeless) and HED Bastognes. Honestly, I do not know which I like better. The DA hub is amazing, and the wheels still have needed zero service after 13k miles. The HED is a new edition so I cannot speak towards long term servicing. I can say, however, that my 25mm Open Corsa are huge on them (in a good way
) and the ride is smooth.
But I am sure someone is going to say ... wait for it ... wait for it ... have a set built.
