Hi,

i am a newbie and would like some advice on 2 bikes i am looking at.

I will be riding primarily paved and on occassion some very easy trails. I guess I am looking fo something light and comfortable. The geometry on the Specialized was fine (i.e. I actually rode this bike a little) I have not tried the Marin yet. I guess I am asking which has the better set of components, and which is the better buy.

Thanks
