We have gone back to the base materials used to produce a carbon-fibre chainring and researched how we can improve these to reduce friction, increase durability and make you faster. Working alongside a British carbon-fibre cloth manufacturer, we have produced our own material infused with a nano-scale friction modifier.\u003c\/p\u003e\n\u003cp\u003eOur own inhouse testing throughout the development process showed an optimal level of friction modifier, resulting in an increase of 0.5% in drivetrain efficiency when compared with a standard carbon-fibre chainring.\u003c\/p\u003e\n\u003cp\u003eThis ultra-high performing chainring was recently utilised by our very own Dan Bigham when setting the new British Individual Pursuit National Record and picking up the gold medal with a 4.05.274, becoming the third fastest pursuiter in history!\u003c\/p\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e","brand":"WattShop","offers":[{"title":"58T","offer_id":58982629278079,"sku":"TRACK-4MM-144-58T-BR","price":200.0,"currency_code":"GBP","in_stock":true},{"title":"59T","offer_id":58982629310847,"sku":"TRACK-4MM-144-59T-BR","price":200.0,"currency_code":"GBP","in_stock":false},{"title":"60T","offer_id":58982629343615,"sku":"TRACK-4MM-144-60T-BR","price":200.0,"currency_code":"GBP","in_stock":false},{"title":"61T","offer_id":58982629376383,"sku":"TRACK-4MM-144-61T-BR","price":200.0,"currency_code":"GBP","in_stock":false},{"title":"62T","offer_id":58982629409151,"sku":"TRACK-4MM-144-62T-BR","price":200.0,"currency_code":"GBP","in_stock":false},{"title":"63T","offer_id":58982629441919,"sku":"TRACK-4MM-144-63T-BR","price":200.0,"currency_code":"GBP","in_stock":false},{"title":"64T","offer_id":58982629474687,"sku":"TRACK-4MM-144-64T-BR","price":200.0,"currency_code":"GBP","in_stock":false},{"title":"65T","offer_id":58982629507455,"sku":"TRACK-4MM-144-65T-BR","price":200.0,"currency_code":"GBP","in_stock":false},{"title":"66T","offer_id":58982629540223,"sku":"TRACK-4MM-144-66T-BR","price":200.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1405\/7098\/products\/WattShopTrackChainring4mm3_15b2d424-f919-48b1-aa4c-2114cfb9efd9.png?v=1793191768","url":"https:\/\/www.shopforwatts.co.uk\/products\/cratus-track-chainrings-pre-oct-2026","provider":"WattShop","version":"1.0","type":"link"}
