Oops, wrong thread. But I might as well ask here too.

Will a Sugino XD2 crankset be a notable upgrade over my current Sturmey Archer FCT-20? I can get a set with a 44t chainring and chainguard, and 42t spare ring for €50. It'll definitely look better on my bike, but I'm not sure if it will have any impact performance-wise?

And is a chainguard cool? Or will it impair my skidz and street-cred?
