They are not compatible with other bikes.\n\u003cp\u003eTrek developed Knock Block as an integrated frame protection system to prevent self-inflicted scuffs, dents, or cracks from spinning handlebars. Knock Block consists of a special stem and a stop chip on the frame. The stop chip limits the turning range of the custom keyed headset cover. The top of the headset cover has notches that lock into corresponding notches on the headset spacers, which also correspond with notches in the stem for a strong connection to the steer tube. These parts work together to prevent the crown of the fork and handlebar controls from hitting the frame when bars are turned too far in either directio. \u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch2\u003e\u003cb\u003eCompatibility\u003c\/b\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eCompatible only with Trek Knock Block\u003c\/li\u003e\n\u003cli\u003eThese spacers have unique raised features that key to Knock Block compatible stems (made by Bontrager)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e1 1\/8\" top (straight 1 1\/8\" or 1 1\/8\" to 1 1\/2\" taper) steerer tubes only\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0230\/9291\/files\/WT_Headset_KnockBlock_stacked_bottom_Stainless_Labels.jpg?v=1591805615\"\u003e\u003c\/h2\u003e\n\u003ch2\u003e\u003cb\u003eRelated Products\u003c\/b\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca title=\"link to Wolf Tooth Knock Block Headsets\" href=\"https:\/\/www.wolftoothcomponents.com\/products\/wolf-tooth-premium-knock-block-headsets\"\u003e\u003cspan style=\"line-height: 1.4;\"\u003eWolf Tooth Premium Knock Block Headsets\u003c\/span\u003e\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cb\u003eTech Specs\u003c\/b\u003e\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e\u003cspan\u003e 10mm\u003c\/span\u003e • 8g\u003cbr\u003e\u003cstrong\u003eMaterial:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e6061-T6 aluminum\u003cbr\u003e\u003cstrong\u003eMade in the\u003c\/strong\u003e \u003cstrong\u003eUSA\u003c\/strong\u003e\u003c\/p\u003e\n\u003cdiv class=\"PdpSqImgLinks\"\u003e\u003ca data-mce-fragment=\"1\" title=\"Wolf Tooth color shop - choose color components for your bike\" href=\"https:\/\/www.wolftoothcomponents.com\/pages\/color-shop\" data-mce-href=\"https:\/\/www.wolftoothcomponents.com\/pages\/color-shop\"\u003e\u003cimg data-mce-fragment=\"1\" height=\"186\" width=\"154\" alt=\"Color Shop - Choose Wolf Tooth anodized color components for your bike\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0230\/9291\/files\/ColorShopButton_0c05b716-d5a6-41e3-9306-7c5aba20041f_480x480.jpg?v=1650986151\" data-mce-selected=\"1\" data-mce-src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0230\/9291\/files\/ColorShopButton_0c05b716-d5a6-41e3-9306-7c5aba20041f_480x480.jpg?v=1650986151\"\u003e\u003c\/a\u003e\u003c\/div\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.wolftoothcomponents.com\/pages\/wolf-tooth-patents-and-trademarks\"\u003ePatent and trademark information\u003c\/a\u003e\u003c\/p\u003e","brand":"Wolf Tooth Components","offers":[{"title":"10mm \/ Black","offer_id":50682519159066,"sku":"SPACER-KNOCK-BLK-10MM","price":1.97,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0688\/4163\/6122\/files\/SPACER-KNOCK-BLK-10MM.jpg?v=1748467429","url":"https:\/\/shop.howlerbikepark.com\/products\/precision-headset-spacers-for-trek-knock-block","provider":"Howler Bike Park","version":"1.0","type":"link"}
