Aero Chain Rings

From: £113.00

NEW – D2Z Aero Chain Rings now also available for SRAM AXS Spyder!

Manufactured in the UK from 6082 aluminium and hard anodised, these circular aero chainrings are specifically designed for use with a single front ring (e.g. 1 x 11) without a front derailleur, which in our testing can give you gains of at least 2.5 watts. The narrow/wide raised teeth design reduces the risk of chain drop. Available with 54, 56, 58, 60 or 62 teeth and 4 bolt Shimano (9100/9200) or 5 bolts (110 & 130 BCD).  Suitable for Shimano R7000, R8000 and Ultegra 6800 chain set. Suitable for 9000 Quarq power meter but not the Giant power meter.

Not compatible with the older Shimano 6700 crank.

If in doubt please refer to the Compatibility Template which can be printed off here.

The challenge with any chain ring is to ensure that it holds the chain as securely as possible to avoid chain drop but at the same time minimise contact (to maximise efficiency). In removing the front derailleur to improve aerodynamics, the chain angle is increased making this even more of a challenge, particularly when the lower gears are used. To counter these issues the teeth on our chain rings are higher than a conventional ring and have an increased chamfer to reduce noise and friction.

When these rings are used in a 1X set up it is often essential to use specific 1X chainring bolts in order to fully secure the chainring to the crankarm.  These can be purchased below.

If the chain ring you require is out of stock please email us and we will notify you regarding lead time.
