When I pedaled mine, there was a very muted "wwwwwrrrrrrr" noise.
You could tell the grease was muting it, somewhat. I could tell the difference,
sort feel the teeth through the pedals a tiny bit. I really think if you keep the
BB tight and the pedals tight on the axle shafts, and keep it greased you'll be OK.
Also, now that I recall, when I 'mashed' as opposed to spinning faster in a
lower gear, the gears complained more. Even though this was most apparent
at the end of its useful life, Im sure it would be a good idea to go a gear
lower when climbing and spin for your speed. Really, just keep everything
tight and ride it. If you are like me and had to commute in New England
snow and then the salt of the Ocean and can make it last, Im sure you will
appreciate it. Also, not getting chain marks carrying it and down the stairs to
my apartment was nice, too
