TA Chinook 4-Arm MTB Outer Chainring
The Chinook 4-Arm is the result of TA’s over 60 years of manufacturing and experience in making high-quality components. Showing off its traditional lathe cut teeth, this model boasts a superior and more precise tooth form in comparison to stamped chainrings. Thanks to its computer-generated tooth profiles, you’ll benefit from optimised power transfer and prolonged drivetrain life, making it the perfect replacement or upgrade for fast and precise gear changing.
Strong and Reliable, Lathe-Cut Chainring
Offering an efficient and smooth experience thanks to its heat-treated 7075 aluminium pick-up pins, this is an excellent addition to any hard-riding MTB drivetrain. Thanks to its stainless steel pick-up pins and machined shifting aids, you’ll benefit from the smoothest changes possible on 9 speed systems, even under power.
