{"product_id":"controltech-ras-23-e-stem","title":"Controltech RAS-23 E Stem","description":"\u003cp\u003eThe Controltech RAS-23 E Stem is designed for cyclists who want a dependable connection between their handlebars and fork steerer while retaining flexibility in cockpit positioning. It is suitable for road, gravel and mountain bikes using compatible conventional handlebar and steerer interfaces. The stem is particularly relevant for riders adjusting their bicycle fit, replacing a damaged component or assembling a custom cockpit. Unlike integrated handlebar systems, its separate construction allows the handlebar and stem to be selected or replaced independently. This makes it a practical choice for cyclists who prefer straightforward maintenance and component interchangeability.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eResponsive Steering.\u003c\/strong\u003e The forged aluminium construction provides rigidity at the connection between the handlebars and steerer. This helps maintain consistent steering feedback during cornering, climbing and out-of-saddle efforts. The faceplate distributes clamping pressure across the handlebar contact area, while the stem body is designed to resist unwanted flex under normal riding loads. Its construction offers a balance between strength and weight without relying on a proprietary cockpit arrangement.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003ePosition and Compatibility.\u003c\/strong\u003e The reversible design allows riders to alter handlebar positioning without replacing the stem. This can help refine reach and upper-body posture when setting up a bicycle for different riding preferences. Before installation, confirm that the handlebar and fork steerer match the specified clamping interfaces. The stem must also provide adequate steerer engagement and clearance around the headset. Correct bolt tightening is essential, particularly when installing it with carbon handlebars or steerer tubes. Follow the component manufacturers' torque recommendations and inspect the assembly periodically for unwanted movement.\u003c\/p\u003e","brand":"Controltech","offers":[{"title":"60 mm","offer_id":48093476126881,"sku":"RAS23E60","price":2099.0,"currency_code":"INR","in_stock":true},{"title":"70 mm","offer_id":48093476159649,"sku":"RAS23E70","price":2099.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0558\/5869\/2257\/files\/controltech-ras-23-e-stem-the-bike-affair-8897837.png?v=1792137306","url":"https:\/\/www.thebikeaffair.com\/products\/controltech-ras-23-e-stem","provider":"The Bike Affair","version":"1.0","type":"link"}
