I don't know if the seatpost will fit as I don't have the bike here now. As for pedals, my concern would be how much that costs me in efficiency - I really have no idea. But I keep a lot of details on my rides and consider a loss of a minute on a normal ride (12.5 miles in usually around 45-48 minutes) to be significant. I mean, I'm trying to get to where I can average 17-19 consistently instead of usually 15-17. Losing a minute matters because I've been stuck for months!
But maybe these things don't matter much - just as weight doesn't seem to matter as much as most people think.
