AbsoluteBlack Narrow Wide Oval Chainring Gravel 110/5 BCD 12 S Grey
absoluteBLACK
Description
AbsoluteBlack Gravel 110/5 BCD 12V Narrow Wide Oval Chainring. A perfect choice for Gravel & Road single chainring installations (1X). Comes with mounting screws for your convenience. The chainring is offset 1.5 mm from the frame for a perfect chain line. Very rigid construction despite the many cut-outs.
Oval chainrings do not produce more force, they increase pedalling efficiency through better transmission of forces. This means that you don't necessarily go further by pedalling harder. But the less force you lose, the more energy you keep, allowing you to pedal harder when you need to and thus reducing your general fatigue. That's why you can ride faster, longer and further with oval chainrings.
Studies conducted by the University of Primorska, Slovenia, show significant differences between the use of AbsoluteBlack Oval chainrings and conventional round chainrings. It is proven that using an oval chainring can provide up to a 9% increase in pedal stroke efficiency, up to 7% less oxygen consumption, 15% less breathing and up to a 10% decrease in heart rate.
Details :
First of all, you need to remove the crank from the bike. Once removed, unscrew the 4 bolts that hold the two original rings together with a T-30 torx key. Remove the two original rings. Place the Absoluteblack oval chainring in place of the large chainring. Please note that the small indicator on the platter should be behind the crank arm - the same way the original platter indicates its position. Use the AB bolts supplied to lock the chainring in place using a T-30 torx spanner with a force of about 5-7 Nm. Reassemble your crank on the bike. Finished
* Always use a new chain with a new chainring.
