While a single-strap shoe like our WorldCup\u0026nbsp;is the undisputed leader for pure speed in transition, the Synchro Aero 4E is designed for “all-out” performance during the bike segment itself.\u003c\/p\u003e\n\u003cp\u003eCombining a dual dial closure system with an aerodynamic cover featuring a medial zipper, this shoe offers the precise and secure fit of a high-end road shoe, with the aerodynamic drag reduction needed for draft-legal triathlons and time trials.\u003c\/p\u003e\n\u003ch3 data-path-to-node=\"4\"\u003eEngineering strategy: aerodynamic priority\u003c\/h3\u003e\n\u003cp\u003e1. Reducing aerodynamic drag through a medial zipper cover\u003c\/p\u003e\n\u003cp\u003eIn a sport where seconds are won over distances from 40 km to 180 km, turbulence caused by dials and components is critical. The Synchro Aero 4E features a smooth fabric cover that encloses the closure system. To further refine the profile, we moved the zipper to the medial (inside) side, away from the main airflow, ensuring a cleaner leading edge on the lateral side of the shoe.\u003c\/p\u003e\n\u003cp\u003e2. Dual lacing system for maximum hold\u003c\/p\u003e\n\u003cp\u003eFor daily road training and high-power races, foot security is essential. The dual lacing system allows independent adjustment of tension on the forefoot and ankle. This provides a level of mechanical “hold” that single-strap shoes cannot match, preventing internal foot slippage during standing efforts on the pedals or high-cadence intervals.\u003c\/p\u003e\n\u003cp\u003e3.

The flat geometry increases pedal contact area, reducing “hot spots” and ensuring every watt of power is transferred directly to the drivetrain.\u003c\/p\u003e\n\u003ch3 data-path-to-node=\"15\"\u003eTechnical specifications\u003c\/h3\u003e\n\u003cul data-path-to-node=\"16\"\u003e\n\u003cli\u003e\n\u003cp\u003eFrame: 100% high-modulus carbon fiber (4E flat-bottom)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eAerodynamic cover: fabric cover with medial zipper for laminar airflow\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eClosure: dual micro-adjustable dials for a precision fit\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eTransition features: medial fly-mount loops; high-strength heel loop\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eColors: Magical White\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eCleat compatibility: standard 3-bolt road\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Cadomotus","offers":[{"title":"EU36|US4 1\/2","offer_id":52841840804187,"sku":"TRI.23.14.36","price":349.0,"currency_code":"EUR","in_stock":true},{"title":"EU37|US5 1\/4","offer_id":52841840836955,"sku":"TRI.23.14.37","price":349.0,"currency_code":"EUR","in_stock":true},{"title":"EU38|US6","offer_id":52841840869723,"sku":"TRI.23.14.38","price":349.0,"currency_code":"EUR","in_stock":true},{"title":"EU39|US6 3\/4","offer_id":52841840902491,"sku":"TRI.23.14.39","price":349.0,"currency_code":"EUR","in_stock":true},{"title":"EU40|US7 1\/2","offer_id":52841840935259,"sku":"TRI.23.14.40","price":349.0,"currency_code":"EUR","in_stock":true},{"title":"EU41|US8 1\/4","offer_id":52841840968027,"sku":"TRI.23.14.41","price":349.0,"currency_code":"EUR","in_stock":true},{"title":"EU42|US9","offer_id":52841841000795,"sku":"TRI.23.14.42","price":349.0,"currency_code":"EUR","in_stock":true},{"title":"EU43|US9 3\/4","offer_id":52841841033563,"sku":"TRI.23.14.43","price":349.0,"currency_code":"EUR","in_stock":true},{"title":"EU44|US10 3\/4","offer_id":52841841066331,"sku":"TRI.23.14.44","price":349.0,"currency_code":"EUR","in_stock":true},{"title":"EU45|US11 1\/2","offer_id":52841841099099,"sku":"TRI.23.14.45","price":349.0,"currency_code":"EUR","in_stock":true},{"title":"EU46|US12 1\/4","offer_id":52841841131867,"sku":"TRI.23.14.46","price":349.0,"currency_code":"EUR","in_stock":true},{"title":"EU47|US13","offer_id":52841841164635,"sku":"TRI.23.14.47","price":349.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0826\/9771\/6059\/files\/Syncro-Aero-road-triathlon-cycling-shoe-main_1980px.webp?v=1776689037","url":"https:\/\/bu-sport.com\/en\/products\/synchro-aero-4e","provider":"BU-Sport","version":"1.0","type":"link"}
