I just told Walter at BF what my gearing is on my Luna, and he took it from there. Of course, it wasn't that simple because my Luna has a compact double and my Friday has a triple, but we got a spread that works for me just fine.

About my white bike--I love how it looks, but it does show dirt, and more importantly, grease. Folding and unfolding results in the chain coming off (unless you're really good at it) and the white bike shows more grease than some people might like. I like black bikes. My partner got a black one (but don't pay extra for the Black Diamond--it's more of a dark grey. The stock Black Ink is really black).
