Can't wait to ride them on a serious weekend warrior ride! But alas, I am a fair weather rider !
I think they will be ok. They haven't held true very well after the trip around the block, so I guess I will be spending some more time trueing, stress relieving, trueing etc. I did build to quite a high final tension, at least by ear, probably not equal enough.
The Mack hub weighs 190 grammes with hardware, that is, bolts, washers and lockring. Exactly as stated by Mack, who is a super nice guy by the way. I even ordered spokes based on his tech sheet because i had to wait so long for the hub to arrive and, surprise, surprise, they were 100% correct!
Without hardware the hub weighs 145 grammes!
