Summary while training and racing
Technical climbs with roots and rocks are much easier to overcome with an oval chainring. When the cadence drops the oval ring increases the drivetrain efficiency by decreasing the amount of time spent in the dead zone. This saves valuable energy per pedal stroke. Overall, during training and races it is a very noticeable effect.
We are both very happy with the SRAM oval chainrings. The ovailty is comfortable while pedalling and technical climbs are much easier. The only negative, is that they take some time to get used to, when switching from round rings. We can only recommend the new SRAM oval chainrings to help better your performance.
