I'm asking because i'm trying to justify the cost, and i don't know if it necessarily equates. I could be wrong, but the weight of the frame seems less important, the difference of the rider weighing 170 or 175 lbs. I feel like the wheels and drivetrain are more important because performance can be more improved through the weight reductions of those components. am i looking at this incorrectly? obviously, at the top tier of racing, you want the lightest frame and every possible technical advantage, but will the more-active-than-average rider really be hindered?
