Hi all,
What a wonderful and helpful forum. I am mainly a runner and swimmer, and recently bought a Lemod Revmaster (spin bike) and fell in love with Spinervals, dvds for cyclists. I am attempting a ride with a cycling group this Monday. I have not been on a bike since a 10 speed when I was 12. The only bike I have is an old Trek Mt bike my sister gave me. The ride leader said it would be difficult on a mt, but I can't afford much now, and plus, what if I don't like it? I called a bike shop and the guy was saying I could put different tires on the mt and that would be better. What do you all think? Can I hang tough with a mt? Do I need the tires? It's not a long ride, just 13 miles I think.

Thanks
Jen
