A central steerer bore and two fork-leg bores are joined by offset arms, clamping both stanchions to the steerer tube. This version is made of 6066 aluminum, with a published weight of 0.488 kg.<\/p>\n<p>The clamp carries impacts from the front wheel and steering torque, with the arms between the bores as the main load path. Al Forge Tech (AFT) closed-die hot forges the clamp so grain flow runs continuously from the center bore to both outer bores, and raises strength with in-house T6 heat treatment. The three bores and clamping slots are CNC-machined after forging, with center distance and parallelism verified on CMM.<\/p>\n<h3>Key Features<\/h3>\n<ul>\n<li>6066 aluminum, 0.488 kg (published specification)<\/li>\n<li>Three bores forged in one piece with continuous grain flow in the arms<\/li>\n<li>Bore spacing and parallelism CNC-machined and CMM-measured<\/li>\n<li>Anodizing for appearance and corrosion resistance<\/li>\n<\/ul>\n<h2>Forged Aluminum Bicycle Triple Clamp (6066) Specifications and Manufacturing Capability<\/h2>\n<div class=\"table-container\">\n<table class=\"table table-bordered table-striped\">\n<thead>\n<tr>\n<th>Item<\/th>\n<th>Details<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Product category<\/td>\n<td>Aluminum Forging Bicycle Parts<\/td>\n<\/tr>\n<tr>\n<td>Application<\/td>\n<td>Bicycle suspension forks, mountain bike and e-bike forks<\/td>\n<\/tr>\n<tr>\n<td>Primary process<\/td>\n<td>Closed-die hot forging (hot forging presses 600T\u20138,000T)<\/td>\n<\/tr>\n<tr>\n<td>Material<\/td>\n<td>6066 aluminum alloy<\/td>\n<\/tr>\n<tr>\n<td>Heat treatment<\/td>\n<td>In-house T4 solution treatment (8 units) and T6 artificial aging (7 units), set by alloy and strength requirement<\/td>\n<\/tr>\n<tr>\n<td>Secondary machining<\/td>\n<td>CNC machining (52 machining centers, 30 lathes), deburring, vibratory finishing<\/td>\n<\/tr>\n<tr>\n<td>Surface finish<\/td>\n<td>Anodizing (including hard anodizing), shot blasting, e-coating or painting, as required<\/td>\n<\/tr>\n<tr>\n<td>Inspection<\/td>\n<td>Zeiss CMM (4 units), hardness testers, spectrometer, fluorescent penetrant inspection line<\/td>\n<\/tr>\n<tr>\n<td>Weight<\/td>\n<td>0.488 kg<\/td>\n<\/tr>\n<tr>\n<td>Dimensions and tolerances<\/td>\n<td>Per customer 2D\/3D drawings<\/td>\n<\/tr>\n<tr>\n<td>Quality system<\/td>\n<td>IATF 16949:2016, ISO 14001:2015<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<h2>Forged Aluminum Bicycle Triple Clamp (6066) Manufacturing Process<\/h2>\n<ol>\n<li><strong>Drawing review and DFM<\/strong>: we confirm alloy, load direction and critical dimensions, then run QForm simulation to predict metal flow and defect risk.<\/li>\n<li><strong>Die design and manufacturing<\/strong>: the number of die sets (for example, blocker and finisher dies) is planned around part complexity, and die contours are checked with a portable 3D scanner.<\/li>\n<li><strong><a href=\"https:\/\/aft-forge.com\/forging-service\/hot-forging-service\/\">Hot forging<\/a><\/strong>: closed-die forming on 600T\u20138,000T hot forging presses creates a continuous grain flow that follows the part contour.<\/li>\n<li><strong>Heat treatment<\/strong>: T4 solution treatment and T6 artificial aging are performed in-house, with parameters set by alloy and strength requirement.<\/li>\n<li><strong><a href=\"https:\/\/aft-forge.com\/forging-service\/aluminum-cnc-machining-services\/\">CNC machining<\/a> and finishing<\/strong>: holes, threads and mating surfaces are machined, followed by deburring, vibratory finishing, shot blasting or anodizing as required.<\/li>\n<li><strong>Inspection and shipment<\/strong>: dimensions, hardness and chemical composition are verified with CMM, hardness testers and a spectrometer, with lot traceability kept under IATF 16949.<\/li>\n<\/ol>\n<h2>FAQ<\/h2>\n<h3>What is the difference between the 6066 and 6061 triple clamps?<\/h3>\n<p>6066 and 6061 are both heat-treatable 6xxx alloys. 6066 has higher alloy content and, after T6 heat treatment, generally higher strength than 6061, suiting designs that need more strength or a smaller section to save weight; 6061 offers a more balanced combination of machinability and corrosion resistance. AFT&#8217;s two clamps use 6066 (0.488 kg) and 6061 (0.518 kg) respectively, to suit the fork design.<\/p>\n<h3>How is positional accuracy of the three bores ensured?<\/h3>\n<p>The three bores set the relative position of both stanchions and the steerer, directly affecting how smoothly the fork works. After heat treatment, AFT machines all three bores in a single CNC setup so they share one datum, then measures spacing, diameter and parallelism on Zeiss CMM and keeps the records.<\/p>\n<h3>Is heat treatment for the Forged Aluminum Bicycle Triple Clamp (6066) done in-house?<\/h3>\n<p>Yes. Al Forge Tech operates 8 T4 solution treatment units and 7 T6 artificial aging units on site, so the Forged Aluminum Bicycle Triple Clamp (6066) can be solution treated, quenched and aged in the same facility before machining and inspection. Keeping heat treatment in-house removes inter-plant transport, reduces lead-time risk and keeps lot traceability within one quality system. Parameters are set according to the alloy grade and your specification.<\/p>\n<h3>How do you keep the Forged Aluminum Bicycle Triple Clamp (6066) consistent from lot to lot?<\/h3>\n<p>Al Forge Tech runs incoming (IQC), in-process (IPQC) and final (FQC) inspection under IATF 16949:2016, supported by 4 Zeiss CMMs, hardness testers, a spectrometer and a fluorescent penetrant inspection line. First, middle and last pieces of every lot are checked against the die; when wear causes dimensional drift, the die is reworked to keep the Forged Aluminum Bicycle Triple Clamp (6066) stable across lots.<\/p>\n<h3>What information do you need to quote the Forged Aluminum Bicycle Triple Clamp (6066)?<\/h3>\n<p>Please send a 3D model and 2D drawing, alloy grade and temper, critical tolerances, surface finish requirements, estimated annual volume and target delivery date.
