IMPORTANT

• Our Sub Compacts chainrings are not compatible with certain power meters which have circular spider design (some Quarq models, Power2Max, etc…) 
• 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.
