T.A have been making chainrings for 60 years. The teeth are cut in the traditional manner on a lathe which produces a much better and more accurate tooth form than stamping, which is used by most chainring manufacturers.
Top Features of the TA 104 PCD Chinook 4-Arm MTB Outer Chainring 42-46T
- 7075 Alloy T6 heat treated
- Arm width 23mm
- Less friction more wear resistance

These are truly TECHNICALLY ADVANCED and are available for most chainsets. Computer generated tooth profiles optimise power transfer and prolong drivetrain life.
Stainless steel pick-up pins and machined shifting aids on the middle and outer rings provide the smoothest changes possible on 8 and 9 speed systems, even under power! Gives fast and precise gear changing.
Chainrings are fitted to the crank arms and come in single, double or triple configuration. Most geared bikes use a 3/32 inch width, whereas 1/8 inch is the popular choice for track bikes and some single speeds due to its increased strength which is needed when riding a fixed wheel. Chainrings are available in a number of formats, these are known as PCD's (Pitch Circle Diameter) or BCD's (Bolt Circle Diameter), this is the spacing of the bolts that secure the rings to the crank arms. Common sizes are 74mm inner ring Shimano MTB, 110mm middle and outer for Shimano MTB, 110mm for most compact chainsets to allow for the smaller ring combo's, 130mm for Standard Shimano Road and 135mm for Standard Campagnolo road chainsets.
