CNC machined 7075 Txxx Aluminum. Long-lasting construction. Type II anodizing

Ovality

50/52/53T - 10-11.2% ; Timing of 108 -110.5° after TDC (top dead center) - Ideal for road climbing. Patent Pending

IMPORTANT

*Ramps on big rings are specially configured for combinations: 50/34, 52/36, 52/38, 53/39T

*34t Premium Series inner chainring is not compatible with power meters that use circular spider (SRAM Quarq, Power2Max, etc). For those power meters please choose our Silver Series 34t inner oval.

*If you wish to use other configuration it will also work, but shifting will be slower and may require more "adjustments" of front dérailleur to be acceptable. Also, remember that front dérailleur can only accept max 16T difference between 2 chainrings - this is how Shimano and Sram designed them.

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