I have a new wheelset with a new Lefty hub and took it out for the first time today. After about 7 miles or so I started to notice a whine from the front hub. The pitch changed with speed but only happens while I'm on the bike (it's silent when I hold the bike and spin the wheel by hand). Any ideas?
