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 48, 50, 52, 54, 56, 58, 60 or 62 teeth and 4 bolt Shimano or 5 bolts (110 & 130 BCD).  

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.

 

  • Narrow/wide teeth pattern
  • Hard anodised for surface colour protection
  • Available sizes: 48, 50, 52, 54, 56, 58, 60 and 62 teeth
  • Higher teeth than a conventional chainring for improved chain retention
  • Large chamfer angle on the teeth to reduce noise and friction through the full range of the cassette
  • Back faces are pocketed to reduce weight

 Chain Ring compatible                                              

  • For chainring compatibility please take a look at our Chainring Templates document
  • Compatible with 10, 11 and 12 speed including SRAM flat top chains. 
  • Please write a customer note at checkout when ordering Shimano 4 x 110 BCD R9200 and R8100 cranksets

SRAM flattop chain

  • We do have people running the SRAM flat top with our chainrings, although the chain may take a bit of running in.  Standard chains are 3.7 mm wide and 2.2 wide. The Sram flat top is 3.5/3.6 and 2.2.  So our rings are a little tight on some teeth to start with.
  • SRAM AXS Direct mount – the only way to use a non-proprietary chain ring is to replace the integrated chain ring and spyder with a separate spyder. Keeping the existing crank.

When these rings are used in a 1X set up it is often essential to use specific 1X chainring bolts to fully secure the chainring to the crankarm, available to order below.  Our stainless steel chain ring bolts are the most durable option, with Allen key heads on both sides. They are supplied with a backing plate/washer for use with a 1x set up.  This helps spread the load of the nut nicely over the spyder, improving clamping force.

We recommend 8Nm of torque for chainring bolts.
