Mountain Biking Slicks?

[melissam]

Any advice on buying slick tires for a mountain bike?

I'm trying to convince one of my roommates to do a charity ride with me in a few weeks. She only has a mountain bike, so I thought it would be easier for her if she traded in the knobby tires for slicks. As a matter of fact, I'll probably ride my mountain bike if she goes on this ride, so I'll be in the market for slicks too.

Performance has a set of slicks for $9.99 each that look like they'd do the job, but I thought I'd ask some of our resident mountain biking experts (Hi Irulan and Adventure Girl, and Lizzie!) if they have any input.

Thanks!
