A word about this rim Alex R390 that comes from the US : beautiful finishing, eyelets without offset, a rather low profile of 19mm and a braking zone reduced to 8mm only !
Eyelets requires nipples of 14mm rather than 12mm which are too short. With 330g this 451mm is not the lightest but undoubtedly one of prettiest.
The Ultegra hub remains as usual : robust, compatible 9 and 10 speed and always a little bit heavy...
