Knock Block consists of a special stem and 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 the strongest connection to the steer tube. These parts work together to prevent the crown of the fork and the handlebar controls from hitting the frame. \u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eDesigned to work only with Trek Knock Block system\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eThe top cap on these headsets have unique raised features that key to Knock Block-compatible stems (made by Bontrager)\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eIf spacers are needed, you will need to use special Knock Block-compatible spacers with notch features\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv class=\"PdpSqImgLinks\"\u003e\n\u003cmeta charset=\"utf-8\"\u003e \u003ca href=\"https:\/\/www.wolftoothcomponents.com\/pages\/headset-fitment-guide\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0230\/9291\/files\/MeasureHeadset_medium.jpg?v=1550605546\" alt=\"\" width=\"155\" height=\"155\"\u003e\u003c\/a\u003e \u003ca href=\"https:\/\/www.wolftoothcomponents.com\/products\/wolf-tooth-precision-headset-small-parts\"\u003e\u003cimg style=\"float: none;\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0230\/9291\/files\/ReplacementParts-Headset_160x160.jpg?v=1590086563\" width=\"155\" height=\"155\" data-mce-style=\"float: none;\"\u003e\u003c\/a\u003e \u003ca href=\"https:\/\/www.wolftoothcomponents.com\/pages\/headset-technical-information\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0230\/9291\/files\/Headset_Tech_c3897e65-a523-4350-8aff-9290078bc929_480x480.jpg?v=1590091876\" alt=\"\" width=\"155\" height=\"155\"\u003e\u003c\/a\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=\"155\" 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\n\u003c\/div\u003e\n\u003cdiv style=\"text-align: left;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0230\/9291\/files\/WT_Headset_KnockBlock_stacked_Top_Stainless_Labels_db559f32-6aeb-41b3-8fd0-003344bc30fc.jpg?v=1613585605\" alt=\"\"\u003e\u003c\/div\u003e\n\u003ch2\u003eRecommendations\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eLower headsets on bikes with Knock Block do not have any unique features, as they are usually \u003ca href=\"https:\/\/www.wolftoothcomponents.com\/collections\/headset-related\/products\/wolf-tooth-premium-is-headsets-integrated-standard\"\u003eIS headsets\u003c\/a\u003e that are available separately.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003eSpecial \u003ca title=\"Wolf Tooth Knock Block compatible headset spacers\" href=\"https:\/\/www.wolftoothcomponents.com\/products\/precision-headset-knock-block-spacers\"\u003eKnock Block-compatible headset spacers \u003c\/a\u003ewith notch features are required if you plan to use spacers.\u003c\/li\u003e\n\u003cli\u003eUpper headsets ship with a star nut which can only be used on forks with steel or aluminum steerer tubes.
