Oval chainring
These oval chainrings have an 11% alternation. This means that the 32 T version has a minimum gearing of 30 teeth and a maximum of 34 teeth. Every pedal stroke encounters a dead point. This is where the cranks are perfectly vertical. You can't exert any meaningful power at that point, so you'll want to get past it as quickly as possible. Oval chainrings have fewer teeth at this point, allowing you to get through it quicker. They then provide you with maximum gearing during the part of the pedal stroke where you can provide the most power. This theory helps you get through the dead spot quicker, meaning you loose less power when you try to reach your optimal power band. This increases your pedalling efficiency, and reduces the amount of lactic acid you produce as well as your fatigue levels. The chainring has an 11% oval shape, which takes a few days of getting used to. Once you have, you'll only be able to ride harder!

Voldoet aan de verwachting
Ik had nog geen ervaring met ovale tandwielen maar de theorie leek me logisch. Het was heel even wennen. Ik merk het verschil voornamelijk in korte klimmetjes over lastig terrein. Daar trap ik wat makkelijker overheen.
Pros
- Eenvoudig te monteren
- Licht
- Goed voor de knieën
Cons
- Prijs
9 / 10
Zeer fijn blad en goed merkbaar met fietsen
Goede kwaliteit en zoals gewoonlijk netjes en snel geleverd.
Pros
- Merkbaar met fietsen
- Kwaliteit is goed
Cons
- Prijs is een klein minpuntje
9 / 10
Aangename verbetering
Na veel lezen en op aanraden van een vriend toch de overstap gemaakt naar een ovaal kettingblad. Qua vertanding niet veranderd, mijn rond kettingblad had 34T en ovaal dus ook hierbij gebleven. Tot nu toe heb ik hier geen spijt van. De eerste meters waren wat vreemd en had ik het gevoel "door te trappen", maar na een paar kilometer begon ik toch een duidelijk verschil te merken qua kracht dat ik kon overzetten. Heb sinds de overstap ook minder last van slapende tenen aangezien ik soepeler kan rondtrappen. Installatie was ook heel simpel aangezien bij SRAM Direct Mount er maar één juiste manier van installatie mogelijk is. Zeer tevreden van de overstap naar ovaal!
Pros
- Bouten met LocTite bijgeleverd
- Klimmen zonder dood punt
- Zo goed als geruisloos door X-sync 2
- Makkelijke installatie
10 / 10
Echt topmateriaal.
Eenvoudig te monteren. Schakeld perfect. Voelt in het begin alsof iemand tegen je been duwt vanachter.
Pros
- Eenvoudige montage
- Efficient
Cons
- Prijskaartje
10 / 10
Werkt goed,geen spijt van.
Werkt zo goed na de eerste rit heeft me maatje hem ook meteen besteld. Dat zegt genoeg. Hoefde overigens niet te wennen hij trapt normaal alleen kun je makkelijker power leveren. Klimmen is net wat makkelijker.
Pros
- werkt
- licht gewicht
Cons
- geen

Sram Eagle Oval Direct Mount Chainring
Description
The Sram Eagle Oval Direct Mount 12-speed chainrings feature the X-Sync 2 technology. The Oval version creates a more supple pedalling motion as you ride your mountain bike. The X-Sync 2 is Sram's name for the latest version of the narrow-wide teeth design. The teeth have been raised and slanted in all directions. This should lead to the chain running considerably quieter while reducing friction at the more extreme chain angles. Parallel to the optimisation of the chain ring tooth design, Sram has also worked on the chain itself with the same goal in mind: creating a quieter drivetrain. The inside of the inner links is fully rounded. No more sharp edges. This offers more free space and makes it easier for the chain to catch and release onto the chainring.Oval chainring
