Most people upgrade to lighter components and/or for better fit. Seatposts generally have a set back - I upgraded to a Thomson because I wanted an inline post. It wasnt any lighter than the one I had originally.
That is assuming that GPS is 100% correct and you take exactly the same route with your car (inlcuding lines through corners etc). When you measure wheel circumference on your bike. Get someone to help you. make mark on tyre and ground. sit on bike and roll forward 1 wheel rev till mark touches ground again. get helper to measure distance.
Icycling had Shimano XT wheels for R3500.00 not too long ago. I reckon that's worth investigating. https://www.bikehub.co.za/forum_posts.asp?TID=64391&KW=
Campy vs Shimano Lance vs Alberto Sram vs Shimano Motorist vs Cyclist 26'er vs 29'er light wheels vs normal wheels Hardtail vs full suspension My vote is for the Anthem.
The 10spd Dura Ace is nice to have. Seeing as you have already got it, you may as well do the upgrade. But dont expect any increase in performance. Maybe in your head you will feel faster every time you look down and see Dura Ace - that's gotta count for something. Convert the Le Jeune to a single speed and gain immeasurable 'cool factor' points. Have your Ridley rebuilt with your 9spd bits and donate it to development cycling and gain even more 'cool factor' points.
Get the Giant Anthem X1 W. Sell something or eat bread and water for a while. I couldnt really afford my X1 (and still cant), but every time I ride it, I realise how awesome it is and it was worth the financial stretch (and stress!)
Why are the Pro III hubs smoother than Pro II's? Different internals? Also, from what I understand, the straight pull wheels (Pro III hubs) come with 85kg weight restrictions. Are SP wheels not as strong? I know they are lighter.
