The crankset I have targeted for myself this year is the Truvativ Firex team with external bottom bracket cups. See it at pricepoint.

Carbon seatposts have always been a problem for me as they tend to be slippery and to slide down. One gets nervous about overtightening the bolt and then............and then..............they get scratched. Ooooooo a scratch in my CF.......will I die?

I just avoid the whole thing and stick with an aluminium seatpost.

The wheelset of the year for last year for me were the Mavic Crossrides at the unbelievable closeout price of $150 (far cheaper than I can build my own) free shipping from Jensen. They were however the previous years model with rim brake rims on disk hubs. After a year of use they have held up perfectly. I don't know how aero the bladed spokes are but Squirrels tremble at their approach.
