Just did! lol

Followup: Just came back from my LBS and all that was needed for the B/B was tightening (the B/B took a full 1/4 turn, and it's probably because of the chain-guard's bracket which is held in place by it). I told the mechanic to take the B/B out, clean everything (B/B, crank, chain, cassette) and also to take the rear hub apart and clean/lube it. Seems that the rear hub, even though was less than 3 months old, was in dire need of cleaning and lubrication.

The was a noticeable difference in the way the bike rolled (less resistance), and the drive-train was quiet and felt sharper than before; or it at least seems like it.
