after searching the forums i didn't really find much to answer these questions:
1 if i'm getting a new crankset, would it be wiser to spend more on the sugino sg75 or is the rd2 sufficient enough? in other words, is the sg75 that much better than the rd2?
2 if i'm looking to lighten up my bike here and there by swapping in carbon fiber parts, which would be best? i was thinking fork and stem, maybe seatpost as well. or is this just futile for city riding?
3a i'm also looking to build my own wheel, preferably going with medium-range hubs (the "please rate cheap track hubs" thread led me to believe that iro, harris, other re-branded formulas, surly, etc are all decent enough hubs for someone who doesn't have the money for phils) and lacing them to velocity aerohead rims. the general consensus is that your LBS doesn't like to be known as "the place with the special tools" or "the place that can fix one small thing on your bike and just get paid for the labor cost" so would it be an affront to my LBS if i went in there with a mostly finished wheel and asked them to tune it up/true it?
3b continuing with the wheel-building, is spoke count a big issue? obviously you want the hubs and rims to have the same spoke count, but is going from a 36 to a 32 really going to make the bike that much lighter or make the wheel that less strong?
