I guess they are ok, don't have them installed yet. Wish they were installed by Poseidon to be honest.

Love these breaks

These are excellent brakes. No issues. Everything worked perfectly with the existing cables and mounts. No bleeding required. The brake feel and power is excellent. As with everything Poseidon sells, it’s good quality and they think about an upgrade path.
