Important

• Our Sub Compact chainrings only work in predefined size combinations. When ordering add 30T and 46T, or 32T and 48T chainrings to your basket or a set. Mounting bolts are included in the price of the small ring.
  
• Due to very special 2.5mm offset construction of BOTH chainrings towards the frame 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
  
• Absolute Black always recommends using a new chain when fitting new chainrings.
  
• SRAM Yaw Front Derailleur Compatibility – Due to the construction of SRAM Yaw front derailleurs, our Sub Compact chainrings are not compatible with them. If you replace your Yaw front derailleur with a Shimano equivalent (there are no indexing issues between Shimano FD and SRAM shift levers) you will be able to use our Sub Compact chainrings.
  

Speed At Cadence Calculation

The absoluteBLACK Sub Compact Oval 46T and 48T rings are large enough to reach comparable flatland speeds as their larger counterparts. This calculation shows gear combinations at 90rpm cadence, and 700c x 25mm tire.

• 46x11T combination is minimally faster than 50x12T. This is 47.5km/h (29.5mph) and is faster than 52x13T! At 100rpm it increases to 53km/h (32.9mph).
  
• 48x11T combination is minimally faster than 52x12T. This is 49.7km/h (30.9mph) and is faster than 53x13T! At 100rpm it increases to 55km/h (34.3mph).
  

As seen from the examples above absoluteBLACK Sub Compact Oval Chainrings are more than capable of reaching high top speeds when used with 11T cog. But where absoluteBLACK Sub Compact rings are in a league of their own is the small 30T and 32T chainring. They make climbing easier and exceptionally comfortable, but still retain high top speeds with 46T and 48T big chainring.

How To Mount

How To Mount Absolute Black Super-Compact 46/30T & 48/32T 110/4 Oval Chainring

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) .
