Proper torque is critical—install to manufacturer specifications to ensure safe towing. Periodically check tightness, especially when hauling loads.  This is normally used for a bicycle with a rear spacing of 148mm and you can validate the thread pitch which is normally printed on your current axle. \u003c\/p\u003e\n\u003ch3\u003eFit \u0026amp; Use Signals\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eEssential for towing Burley child trailers or cargo trailers\u003c\/li\u003e\n\u003cli\u003eIdeal for gravel and road bikes used for family or utility riding\u003c\/li\u003e\n\u003cli\u003eCommon upgrade for modern bikes with thru-axle rear ends\u003c\/li\u003e\n\u003cli\u003eRequired component when converting from QR to thru-axle trailer setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv style=\"display: none;\" data-ai=\"mechanic-insight\"\u003eThis is a precision-fit product—most returns come from incorrect thread pitch or axle length. Customers often assume “12mm is enough”—it’s not. You must match pitch (1.5 here) and length range. Always have them measure or pull the existing axle markings. Some frames (especially Trek, Specialized, Giant) use proprietary lengths—double check. Also watch derailleur hanger integration—make sure the axle fully seats without binding. Upsell opportunity: Burley hitch kit if they don’t already have one, and thread grease to prevent seizing over time.\u003c\/div\u003e","brand":"Burley","offers":[{"title":"Default Title","offer_id":53284492771642,"sku":"GG-AXLE-BURLEY-THRUAXLE-12X15-172178","price":64.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0745\/5735\/8394\/files\/FS0619.jpg?v=1775573945","url":"https:\/\/gograva.com\/products\/burley-12x1-5-thru-axle-adapter-172-178","provider":"Grava Adventure Corporation","version":"1.0","type":"link"}
