I've never looked at Jamis so can't say anything at all about them. Cannondale's smalled WSD bike is has too high of a stand over height for me to even bother with. Also the smallest men's frame which is what my husband bought just never fit him right and we ended up selling it. We are in process of buying him a Felt which is in layaway and we are paying on it. So that's our experience with Cannondale.
