Advice on fitting a HeliCoil
Chaps, I'm pretty sure experiences will be thin on the ground, but I will try nevertheless... my Cannondale Lefty spat out its helicoil - I've found a forum suggesting to get a m10-1.0 replacement coil. I did this, bought 10 in fact. They go in smooth, but the moment I try to fit the wheel back the nut seems to really struggle and if I remove the wheel the coil starts to come out with it.
So if anybody has some experience with this please let me know how I can fix this. I've wasted 5x of my replacements thusfar......
