This effectively reduces the dead spot and ensures flawless chain retention, similar to our round rings. By shortening the dead spot on the top and bottom of the power curve, you can get back into the power phase of your crank rotation sooner, resulting in two benefits: increased gearing on the downward stroke and a faster crank speed to continuously propel the crank back into the power phase. This is a significant advantage as studies have shown that at least 80% of pedalling power is generated from the downward motion, which utilizes larger muscle groups. The use of physics sorcery adds extra power to the downward stroke without requiring any additional effort, thanks to the reduction of the dead spot and the increased gear size during the larger power phase in the downward stroke. It's a win-win situation.\u003c\/p\u003e\n\u003cp\u003eAll of our Chain Rings are + \/ - 2 Teeth so;\u003c\/p\u003e\n\u003cp\u003e30T Has a combination of 32T Increased Power Phase and 28T Dead Spot\u003c\/p\u003e\n\u003cp\u003e32T Has a combination of 34T  Increased Power Phase and 30T Dead Spot\u003c\/p\u003e\n\u003cp\u003eWe would recommend sticking to the current sized round ring that you are currently using when selecting your Oval size.\u003c\/p\u003e\n\u003ch5\u003eKEY FEATURES\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003eThick Thin Tooth Profile\u003c\/li\u003e\n\u003cli\u003e10, 11 and 12 Speed Compatible\u003c\/li\u003e\n\u003cli\u003e115 Degrees of Ovality\u003c\/li\u003e\n\u003cli\u003eFully CNC Machined from 7075 Aluminium\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Burgtec","offers":[{"title":"30T \/ Black","offer_id":42113075052614,"sku":"BUR-8841","price":94.99,"currency_code":"AUD","in_stock":true},{"title":"30T \/ Bullion Gold","offer_id":42113075085382,"sku":"BUR-8855","price":94.99,"currency_code":"AUD","in_stock":true},{"title":"30T \/ Deep Blue","offer_id":42113075118150,"sku":"BUR-8845","price":94.99,"currency_code":"AUD","in_stock":true},{"title":"30T \/ Iron Bro Orange","offer_id":42113075150918,"sku":"BUR-8851","price":94.99,"currency_code":"AUD","in_stock":true},{"title":"30T \/ Purple Rain","offer_id":42113075183686,"sku":"BUR-8847","price":94.99,"currency_code":"AUD","in_stock":true},{"title":"30T \/ Race Red","offer_id":42113075216454,"sku":"BUR-8843","price":94.99,"currency_code":"AUD","in_stock":true},{"title":"30T \/ Rhodium Silver","offer_id":42113075249222,"sku":"BUR-8853","price":94.99,"currency_code":"AUD","in_stock":true},{"title":"30T \/ Toxic Barbie Pink","offer_id":42113075281990,"sku":"BUR-8857","price":94.99,"currency_code":"AUD","in_stock":true},{"title":"32T \/ Black","offer_id":42113075314758,"sku":"BUR-8842","price":94.99,"currency_code":"AUD","in_stock":true},{"title":"32T \/ Bullion Gold","offer_id":42113075347526,"sku":"BUR-8856","price":94.99,"currency_code":"AUD","in_stock":false},{"title":"32T \/ Deep Blue","offer_id":42113075380294,"sku":"BUR-8846","price":94.99,"currency_code":"AUD","in_stock":true},{"title":"32T \/ Iron Bro Orange","offer_id":42113075413062,"sku":"BUR-8852","price":94.99,"currency_code":"AUD","in_stock":true},{"title":"32T \/ Purple Rain","offer_id":42113075445830,"sku":"BUR-8848","price":94.99,"currency_code":"AUD","in_stock":true},{"title":"32T \/ Race Red","offer_id":42113075478598,"sku":"BUR-8844","price":94.99,"currency_code":"AUD","in_stock":true},{"title":"32T \/ Toxic Barbie Pink","offer_id":42113075511366,"sku":"BUR-8858","price":94.99,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/3081\/4790\/files\/BUR-8841.png?v=1736132836","url":"https:\/\/crooze.com.au\/products\/burgtec-thick-thin-hope-boost-direct-mount-oval-chainring","provider":"Crooze","version":"1.0","type":"link"}
