I've been out of the bike scene for quite some time and I've been shopping hard for a bike so I can ride with my 8 year old at the skate park and downtown street spots. I sort of have my eye on the fit prospect and the cult gateway but I don't think either are full chromoly. I'm 33 and won't be doing anything crazy like I used to so I'm not sure if full chromoly will be necessary. Any help would be appreciated.
