I was informed by TerraCycle that the tapped Glide flex hole is NOT intended to "fix" the angle, but only to preload the delryn washer to give some drag. Since I also wanted to fix the angle on the Glide Flex that I used (reversed) on my daughter's lowracer, I was told by TerraCycle to use a longer bolt and a nylock nut on the end. (They supplied me both at no charge). Works as advertised- but I did tell them what I wanted to do.Can't complain that it doesn't work if you don't use it like it was intended- and without telling them what you wanted .
