Affectionately known as the "panini press", this veratile toolspans the entire saddle and is precisely weighted to sit securely while you read the seat angle with the digital level. It also gives you a good sharp edge to measure from the center of the bottom bracket to the top of the saddle. The digital level is held onto the main plate by it's magnetic base. This allows you to detach the level and use it to measure handlebar angle as well as other frame angles.
