Direct mount Oval chainrings are designed for Sram DUB, GXP and long BB30 spindle cranks (15.4mm axle spacer on drive side) Oval chainrings work because a rider does not produce power evenly through a pedal stroke; they maximize the part of the stroke where power is produced and minimize resistance where it isn't. Oval rings make the spin cycle a lot smoother and are easier on legs while climbing. Believe it (or not), but a round chainring doesn't transfer torque to your rear wheel as smoothly as an Oval one. You will actually feel your stroke to be more "round" with an Oval shape than with a round chainring.
Why it matters ? Traction, Traction and Traction. With oval rings, rear tire traction improves greatly on loose and slippery terrain. Your legs will be less tired and your speed improved. Climbing will become easier then ever before. It is world's best oval chainring.

Bonjour, Est ce que ce plateau oval avec un offset de 6 mm convient à une transmission NX Eagle 12v non boost monté sur un VTT non boost ? Ou faut il que je m’oriente vers un offset de 0 mm ? Merci pour votre réponse.
Bonjour
Les plateaux avec 6 mm de déport se montent sur les cadres non boost effectivement. Le 0 mm se monte sur les cadres au format BB30 ou Super Boost
