If so read on.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eThrough research and testing of many different prototypes with varying amounts of Ovality we found 115% (from the top centre) to be the optimum.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eThis shrank the dead spot suitably and gave the same flawless chain retention and silence as our round rings.  The shortening of the dead spot on the top and bottom of the power curve allows you to get back into the power phase of your crank rotation sooner.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eThe benefit of this is twofold; increased gearing on the downward stroke and faster crank speed to get the crank propelled back around into the power phase continually. This is a significant gain because virtually all studies into pedalling performance suggest that a minimum 80% of your power  comes from the down ward motion. Mainly because much larger muscle groups are used for this motion. The physics sorcery essentially adds extra power in the down wards stroke for no extra effort by reducing the dead spot and adds a bigger gear for the now larger power phase in the downward stroke. Win win.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eAll of our Chain Rings are + \/ -  2 Teeth so;\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e30T Has a combination of 32T Increased Power Phase and 28T Dead Spot\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e32T Has a combination of 34T  Increased Power Phase and 30T Dead Spot\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eWe would recommend sticking to the current sized round ring that you are currently using when selecting your Oval size.\u003c\/p\u003e\n\u003cul data-mce-fragment=\"1\"\u003e\n\u003cli data-mce-fragment=\"1\"\u003eThick Thin Tooth profile with Mud Bleed\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003e10 11 and 12 Speed Compatible\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003e115 Degree’s of Ovality\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eFully CNC Machined from 7075 Aluminium\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cbr\u003e \u003c\/div\u003e\n\u003cp\u003eArtikelnummer: 0712885684670\u003c\/p\u003e\n\u003cp\u003e\u003cbr data-mce-fragment=\"1\"\u003eLieferumfang: Kettenblatt\u003cbr\u003e\u003c\/p\u003e","brand":"Burgtec","offers":[{"title":"30T \/ schwarz","offer_id":45066704126216,"sku":"0712885684670","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0445\/6461\/1239\/files\/IMG_3551_a22f32af-dcd8-42a6-8b9f-b167b398249f.jpg?v=1704879267","url":"https:\/\/rtfbikepirtsde.com\/products\/burgtec-oval-96-64-thick-thin-kettenblatt-30t-black","provider":"RTF Bikeparts","version":"1.0","type":"link"}
