Due to very special offset construction and custom bolts:

*30T can only work with 46T and special bolt set 46/30. (bolts included with small ring)

*32T can only work with 48T and special bolt set 48/32. (bolts included with small ring)

*No other combination or mix of rings will work. Due to special mounting construction, aesthetic bolt covers are not offered for this design

*We Only recommend Dura-ace 11spd chain or Sram Eagle 12spd chain for proper clearance of mounting tabs

Advantages of Absolute Black sub-compact Oval chainrings:
  • 30 and 32T chainrings allow you to climb on your own terms with improved cadence and efficiency
  • One of a kind special oval shape that helps you climb easier and faster (Patent Pending)
  • No more mashing on long climbs and wishing for bigger cassette.
  • Have you ever had to walk the climb on sportive race? These rings will save you from it.
  • 46/11 or 48/11 is still a big gear to push on the flat. For your daily ride you most likely don't need more
  • Your pedaling will feel smoother
  • AB oval reduces stress on knees and helps your legs remain fresher for longer
  • You will be able to maintain better cadence while climbing
  • Reduces possibility of leg cramps

What size should I choose?

*46/30T is best for great gravel adventures where lots of climbing is involved and bike is packed with gear. Or simply for you to actually enjoy road climbs like Sa Calobra in Majorca or Alpe d'Huez in France

* 48/32T is ideal for general road climbing and day to day riding. Planning L'Étape du Tour? This size is right for you (30T would be too slow).

How to mount super compact 46/30T & 48/32T 110/4 Oval chainrings:
First, you need to remove your crank from your bike. Once removed, unscrew the 4 bolts that hold two chainrings together with a T-30 torx key. Remove both original rings. For 46/30T - Start by placing big chainring on the crank. There is only one way to do it. Next locate triangular mark on inner circumference on the small chainring and make sure it will sit behind the crank. Small chainring has also integrated spacers on one side. Those spacers need to enter into the crank mounting holes. 30T chainring is provided with 2x M5 bolts (Torx T-25) and 2x M7 bolts (torx T-30). Lock both chainrings in place using provided bolts and torque M5 to 4-5Nm and M7 to 5-7Nm. For 48/32T - Same procedure applies except that 32T chainring comes with 4x M7 bolts (torx T-30).

Absolute Black always recommends using a new chain when fitting new chainrings.

This ground breaking construction has patents pending in several countries around the World. 

Occasionally, without notice, manufacturers change product design and/or specifications.

Excellent chainrings
by Sean B on 03/09/2019

Fitted to 105 R7000 cranks along side an R7000 front mech and running and shifting is as good as with the standard chainrings. Not the cheapest but when you consider standard replacement rings are £60+ and these are oval and the only sub compact option available for compact road cranks it becomes slightly easier to stomach.

Great Concept
by Anonymous user on 05/03/2019

Great idea, engineering and concept. The rings work but they are way way over priced for what they are. A pair should be £65 not £140. Beware - there is not enough adjustment on the low hex screw on a R7000 front derailleur. They should be perfect for the price and not just about work. I do feel a triple with chain guard on outer is a better solution.

Don't fit
by James M on 27/09/2018

The only way to check if these will fit is to try to fit them and once fitted they are "used" so can't be returned. The chain line is mov 3mm inboard so make sure you have clearance with the chainstay
