I have sram on my old XC bike, and my AM bike. My Road bike and AM bike have Sram cranks, and they both are squiking.
I like Shimano! Only reason i would want to change the Shimano crank ( which i allready posess) Is if it has a big weight penality.
My weight now is heavy.. that is one of the reasons i'm racing next year. To loose weight.. So im abit scared of carbon wheels etc. If they have a weight limit close to my weight then im not interessed.
I weigh 104kg/229lbs now, and i want to go down to 90kg/200lbs until the last big race in August 2014.
My road bike have wheels with 130kg weight limit, and they feel flimsy and bad compared to a weelset without restrictions
The definition on CX is pretty much dropbars. Thats the best about CX, other than that a 29er will be just as fast? Just find a low bb 29er frame and im ready to eat milage.
I think i have settled on 29er though. Everyone else is using it, One guy i saw out of 14 000riders in the last race used a CX with flat bars. My guess is super fast in the easy parts, and super slow in the "technical" parts ( Loose gravel, nice trails w/ an occasional rock and root)
A friend have a unused DT Swiss wheelset for sale aswell... might buy that, he says it is 1450grams..
