This is integrated only — bearings sit directly in the frame.\nIS42 upper \/ IS52 lower is critical. If the frame isn’t machined for this, it won’t fit.\nShort top cover keeps stack low, but sometimes customers expect spacers — that’s not what this does.\n40 Series bearings are solid. Not boutique smooth, but durable and easy to replace.\nFailure points usually come from dirty bearing seats or dry crown race installs.\nRiders like how quiet these stay compared to cheaper OEM headsets.\nComplaints usually come from wrong sizing or neglected maintenance.\nWho this is really for: trail, gravel, commuter riders replacing worn OEM headsets.\nWho should avoid: anyone needing ZS\/EC cups or running straight steerers.\nMechanic advice: clean frame bearing seats, lightly grease contact surfaces, press crown race square, and recheck preload after first ride.\n\u003c\/div\u003e","brand":"Cane Creek","offers":[{"title":"Default Title","offer_id":53070619803962,"sku":"CC40-IS42IS52-BLK","price":69.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0745\/5735\/8394\/files\/35759.jpg?v=1771804101","url":"https:\/\/gograva.com\/products\/cane-creek-40-series-integrated-headset-is42-is52","provider":"Grava Adventure Corporation","version":"1.0","type":"link"}
