Using our experience and vigorous testing, we tweaked the arm design and strategically machined the chainrings so that only minimal sacrifices were made in impact strength in exchange for large gains in weight reduction With unique tooth profiles, mount and climbing aids allow chainrings a particularly soft and fast switching. So with them a shift under load easily. The chainrings have been specially tuned by climbing aids and can only achieve their superior shifting performance in the combinations provided The chainrings are CNC machined from 7075 T6 aluminum and hard coat industrially anodized to provide protection from mechanical impacts, a good look, and an excellent tactile feel to each of the chainrings that lasts a long time A unique tooth profile eliminates chain noise, reduces wear, and provides smooth operation on the entire system of all the most common combinations of drive trains The tooth profile is specially designed for use with Road chains chainrings are the best choice if you are looking for a technologically sound chainring with a unique design and low weight RECOMMENDATIONS For the best appearance, you may use AERO COVER (for 105 R7100, Ultegra R8100, R8100-P or Dura-Ace R9200, R9200-P cranks) Also, you may use chainring bolts and nuts for mounting: 7mm nuts and 6,5mm bolts are required It is also a good idea to use a new chain with your new chainrings It is recommended to use a well-lubricated chain on every ride We recommend using the optimal 2-speed chainrings combination The correct operation of the double set is guaranteed only when using outer and inner chainrings together Tool holder: 5 mm hexagon socket maximum permissible torque: 10 Nm
