Bontrager has great technical support! I have a carbon stem on my road bike and I wanted to know the maximum tightening torque for the bolts on the stem. Even though this is an essential piece of information needed to avoid cracking the carbon, it strangely is not present anywhere in the documentation. Nor, apparently, anywhere on the web. So I decided to call Bontrager's technical support center, and I was pleasantly surprised. No voice menus. No asking me for my name or any other personal information. A guy simply picked up, I told him my problem, and after a second of thought, he gave me the answer. Which is 60 inch-pounds for anybody else who needs to know (this is for the Race XXX Lite stem).
