I'm happy for the folks here who have had such positive experiences with the SP hubs. I wish I could say the same!
My SP SV-9 had significantly more drag than my SON hubs when first delivered. I hoped it would wear in, but it hasn't. Instead, it's gotten much worse. As of this morning my SP hub has more drag unplugged and under no load than my SON hubs have with headlight and tail lights on! I just shot a little video to show the issue: https://www.youtube. com/watch?v=g5YBals43L8 I'll also note that the SP SV-9 needs to go about 30% faster before powering the headlight without flickering compared to my SON Delux Widebody SL hubs. Cycle Monkey, who does USA warranty support for SP, has been very responsive but they do require me to unlace the wheel to get the hub replaced. I'll then face the question of whether to ask Rich to rebuild this wheel with used parts or just to replace everything. And then there's Rich's wheelbuliding feel, of course. In the end, this is going to be much more expensive than it would have been to simply go with another SON hub. Wish I'd done that.
