TA Nerius 11x Campagnolo CT chainrings review£109.98

Aftermarket rings

BikeRadar score4.5/5

Made from 7075 aluminium alloy that's stage heat-treated to T6 hardness, these TA chainrings have great resistance to wear, but also shift just as well as the standard Campagnolo Record 11-speed rings they replaced – with a saving of nearly £70 per pair.

The inner rings are available with 34 (31g), 36 and 39 teeth, and the outer rings in 48, 50 (76g), 52 and 53. That’s more choice than Campagnolo offer with their chainrings, and these have the added benefit of being able to run quite happily on older compact 10-speed cranks from Campagnolo (110mm bcd), allowing you to convert that style of crank to 11-speed.
