I am in the process of swapping out my Shimano 105 cranks for FSA Carbons. I just got a torque wrench and will use it often for repairs. I remember when I first replaced my seat post (the one that come with the bike was a tad too short, so I swapped out my old beater bike post), It has a smaller diameter and I really ratched it down to keep it from slipping. When I visted the bike shop the guy told me to get the right diameter post and don't over tighten it or I could crack my carbon frame. I have since found a nice Specialized Carbon seat post and did not over tighten it (just snugged it). Now that I have a torque wrench I can verify its tightness is correct. Good thread!
