CORONA OVAL BURGTEC OVAL THICK-THIN GXP BOOST 3 MM OFFSET
The CORONA OVAL BURGTEC OVAL THICK-THIN GXP BOOST 3 MM OFFSET offers the mechanical advantage of greater transmission. Through numerous tests of prototypes with varying degrees of ovality, it has been found that 115% (from the center upwards) is optimal. This adequately reduced the dead spot and gave the same perfect chain retention and quiet operation as round chainrings. The shortening of the dead spot at the top and bottom of the power curve allows returning to the power phase of pedal rotation sooner.
OVAL BURGTEC OVAL THICK-THIN GXP BOOST 3 MM OFFSET MAIN FEATURES:
- All Burgtec chainrings are +/- 2 teeth, so: 30T has a combination of increased power phase 32T and dead spot 28T. 32T has a combination of increased power phase 34T and dead spot 30T.
To choose the right chainring, refer to the currently mounted one. - Thick and thin tooth profile with Mud Bleed.
- 10, 11 and 12-speed compatible.
- 115 degrees of ovality.
- Fully CNC machined from 7075 aluminum.
