This strategic shift wasn’t just aesthetic it was driven by performance precision and practicality. The mono-riser design emerged from extensive CFD simulations and wind tunnel testing. By consolidating the riser structure into a single central pillar Vision engineers dramatically reduced frontal surface area and turbulence around the cockpit zone. This cleaner airflow translates into measurable aerodynamic gains especially critical in time trials and triathlon racing where every watt and second counts.\u003cli\u003eHigh-modulus carbon construction wing\u003c\/li\u003e\u003cli\u003eNormalized fit increments in every dimension\u003c\/li\u003e\u003cli\u003eEasy adjustability with no occluded bolts\u003c\/li\u003e\u003cli\u003eInternal cable routing and Di2 compatible\u003c\/li\u003e\u003cli\u003eStem length: 90mm\u003c\/li\u003e\u003cli\u003eBase bar width: 400mm (c-c)\u003c\/li\u003e\u003cli\u003eAdjustable stack height: from 5mm to 95mm\u003c\/li\u003e\u003cli\u003eSpacer stack included\u003ctable border=\"1\" cellpadding=\"5\" cellspacing=\"0\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eCarbon\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColor\u003c\/td\u003e\n\u003ctd\u003eCarbon\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDefined Color\u003c\/td\u003e\n\u003ctd\u003eCarbon\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/li\u003e","brand":"Vision","offers":[{"title":"Default Title","offer_id":52979588661530,"sku":"HB1821","price":593.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0688\/4163\/6122\/files\/7efc4e8e3927c21a5d3b823658ab4a0ce33fc9ea.jpg?v=1790819775","url":"https:\/\/shop.howlerbikepark.com\/products\/vision-metron-tfa-evo-base-bar-high-modulus-carbon-400mm-width-90mm-stem-adjustable-stack-5-95mm-blk","provider":"Howler Bike Park","version":"1.0","type":"link"}
