Absolute Black Mountain Chainrings
Absolute Black Road & Track Chainrings
- Inner and outer oval chainrings are optimized with smooth shifting in mind
- Features smooth angled surfaces, (6) up-shifting ramps (outer ring), and (12) down-shifting points (outer ring)
- Oval rings help the rider to spin smoother and more efficiently
- Example: 32t is equivalent to 30t at dead spot and 34t at the power zone
- Works with 2x chainring systems and does not require any modification to the front derailleur for use
- Compatibility: Shimano Dura-Ace 7900,7950,7800, Ultegra 6750, Shimano 105- 5700, Tiagra 4650, FSA, S-works and many more older cranks. Also fits SRAM Force and Red, but not compatible with SRAM cranks that have (1) hidden chainring bolt (Force22, Red22)
- Outer chainring requires long bolts. If using inner oval ring only, stock bolts will work
- Designed in UK, manufactured in Poland
