My finalists are pretty spread out but here is what I'm thinking in no order:
Cinelli Caleido Ribbon - I like the dots showing through a different color idea and that they are all different colors adds a bit of fun, but is still subtle from a distance.

Specalized s wrap roubaix type in pink - I'm not a total pink girl but I think this shade of dark pink would be ok with the navy on my bike since it's not too light.

Something along the lines of the fi'zi:k Microtex tape in green. This would stand out, and I really really like the idea of it, but unsure of how I would like it actually day in day out.
