What size should I choose

  • 42T Oval chainring has an ovality of 40/44T and is best for someone who uses currently 41 or 42T round ring.

Why our oval chainrings work

Our premium 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. Smoother power delivery to your rear wheel means that you will be able to maintain better, constant cadence; get less stress on the joints (knees) and therefore be able to keep certain level of effort for longer. This results in higher average speed. Moreover, 11 studies made by various Universities in the World show that using oval chainrings human legs utilize more muscle groups (compared to round one), but each of them to lesser degree. Load from pedaling an oval chainring is spread over greater muscle mass which in effect gives you the feeling of fresher and more relaxed legs. It is world's finest oval chainring backed by tens of thousands of customers.

How to mount Direct Mount Chainring

First you need to remove crank from the bike. Once removed, unscrew 5 bolts that hold two rings together with T-30 torx key. Take off both original rings. Position Absoluteblack oval chainring in place where the big chainring was (outside position). Please note that small indicator on the chainring Must sit behind crank arm - same way as original chainring indicates its position. Use the included bolts to mount your new ring on the crank and close back those four bolts with force of about 5-7Nm. Mount your crank back to the bike.

Bonjour Quelle est la dimension de la clé pour serrer les vis fournies ? J'ai essayé plusieurs taille de BTR mais aucune ne fonctionne... Merci d'avance

Réponse de Purebike 29 Mai 2020

Bonsoir

Les vis fournies sont des vis TORX qu'il convient de serrer avec une clé TORX T30. L'utilisation d'une clé BTR risque d'endommager les vis et ne permettra pas le serrage au couple préconnisé
