My seat is set about 4" above the bars. I used to own a Jamis Quest with a slightly larger frame and lower seat; I wasn't a whole lot lower in the drops than I am on the Coda.
If I had to choose one from SlimRider's list based simply on "go fast," it'd probably be the Sirrus Pro. It's the most "roadie" of the bunch - thinnest tires, nice road-oriented cockpit and I suspect it's the lightest of the bunch. Not that I'd go there - it ain't steel
- but it sure looks sexy and I bet I'd be pretty fast on it. Until my back started whining.
