Rear wheel resistance and vibrations are driving me crazy I've recently purchased a new wheel set for my track bike. It's a Phil Wood High Flange laced to H + Son Archetype. 

I've been traveling a bit and haven't really ridden them very long. I immediately set them up on my bike and rode them the following day on a 40 mile ride. Halfway through through my ride I started feeling a bit of resistance, as if someone was holding me back, causing me to use use more energy and slowing me down. 

I pulled off, checked chain tension, alignment and wheel rub (no brake rub because I ride brakeless) but everything was fine. I've read on here of similar scenarios from other riders however, many said they were going a particular speed. Somewhere between 20-30mph. Mine is on and off, the resistance does pick up on elevated speeds but for the most part it holds me back.

Today I went for a ride, looked over the rear wheel especially and again, everything checked out totally fine. Though, it went straight into the same issues as before. Only on my way home my rear wheel actually somehow loosened and had major wheel rub. I pulled over and realigned the wheel and tightened. It didn't happen again.

If anyone can give some suggestions or opinions I'll really appreciate it. Cheers
Check if the bearings are worn. I know its new but it's worth checking. If there's no grease on the bearings, apply some grease on the bearings and install the wheel back. But before doing that, check if the bearings were screwed in too tight. if that doesn't make any sense to you, I apologize.
