Well here she is.

I basically did my commute (not a work day but the LBS is a block from work) plus about a mile or two extra for good measure. That's about 15 miles of riding so far.

First impressions, and this is coming from a Liquid 25, which was a monster SUV of a mountain bike:
1) It's light! (Lighter than the Liquid, anyway.) Steering was was far more responsive. She flicks really nicely.
2) Faster. Definitely faster. I was the fastest guy on the MUP. Even with the headwind I was zipping right along. I need to put my speedo on to see just how much faster.
3) The 8-speed hub was fine for my ride. There's one uphill and first gear was nice and easy. I was following a guy on a mountain bike and having no issues. I never needed the top 2 or 3 gears on the flats, but I can see using them on downhills. My ride TO work includes a more serious climb so I'll get a better feel for that on Monday.
4) Brakes: Rear drum was anemic compared to the hydraulic disk on my Liquid. Not a surprise. Okay for bleeding some speed. Front disk is required for real-world use. All around, braking was good though. No complaints.

So that's about it for now. If anything happens, bad or otherwise, I'll post. Oh yeah, there was one thing I decided I need: Toe clips.
