Purchased after using a short expander plug that that kept loosening and caused the ring of death on a fork. The Ancora plug and it's length have all contact points and clamping holding solid. For the folks that have had cracking issues. You should find out what torque setting the carbon manufacturer suggest. The fork I have is a 5.5nm torque and have had no slipping or loosening issues. Highly recommend the Ancora.

Long body means effective contact with carbon steerer, which are prone to slipping.

Well made, easy to use and secure lock without damage to the carbon steerer tube.

Great product

This is so much nicer than the preload plug that came with my bike. Highly recommend!
