Thanks. I did order a pair. I also found a guy on eBay selling 3d printed aero plugs for the base bar.

For worry-free use, use sealed hubs, as topflightpro suggests.
Yes! I bought them used from NJS Export and the cones were mildly pitted. Just get a hub that uses sealed bearings... It's less of a headache.

What's the difference between the Origin and Science Track SRM Power Meters? I use a Power Control 7 computer.

The main stuff
- Available Crankarm lengths (more "arms" on the science and you can buy shorter arms, but you get the look style adjustable 170/172/175 on the origin)
- Different Bottom Bracket Standard
- +/- 1% accuracy on the Origin vs. .5% Science
- Maybe the biggest, you can recharge the Origin, vs having to send the science off to SRM to have the battery changed (or hacking / soldering a new battery in yourself)

If the crankarm length and Q-factor will work with the Origin, it's a lot easier to live with vs. the Science.

*Something random I noticed perusing SRM's site lately is that they now offer a "rechargeable battery" upgrade to existing SRM's, including the track models. A bit pricey, but so is shipping your SRM off every year or so.

I sent one of my SRMs in a couple weeks ago for a new battery. They offered to switch me to rechargable for $450. I opted to just go with the batter replacement and leave it as is.
