TRUVATIV self extracting bolt woes
I'm at my wits end people. My TRUVATIV Stylo carbon crank (06 model) recently came loose. When I went to tighten it I heard a pop and the wrench continued to spin. I took the left arm apart, including the self extracting bolt and cap only to find that the bolt was stripped. No problem. I had another laying around which I tried to put on with the same results, plus it broke. I looked at the spindle and that looks good, but for some reason the bolts keep getting stripped. I'm not using a torque wrench, but I'm also not tightening beyond the crank being snug. So basically the crank never gets tight enough no matter how much pressure I apply and then the bolt strips or breaks. Any ideas oh mighty crank masters?
I'm using a truvativ stylo high modulus carbon crank with an external gxp bb.
