This describes the use of both angular contact bearings \u003cstrong\u003eand\u003c\/strong\u003e angled bearing cups\/hub bores used in the hub design.\u003c\/p\u003e\n\u003cp\u003eThe AC-2 hub features revolutionary bearing installation and function never seen before in a bicycle hub.\u003c\/p\u003e\n\u003cp\u003eIt has been designed from the ground up for ease of maintenance and optimal bearing performance.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eHere are a few key points of the AC-2 BMX Front Hub:\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003e-The AC-2 hubs use 20mm Angular Contact bearings with a wave spring pre-load. Bearings are pressed into tapered cups that mate with the angled bores machined into the hub shell. This design feature allows bearing\/cup to be easily installed and removed from hub shell \u003cstrong\u003ewithout \u003c\/strong\u003eany special tools. No more presses or hammers needed! Another attribute of the tapered bearing cup\/angled hub shell bore design is how the bearings seat in the hub. The bearings\/cups on each side of the hub shell are in \u003cstrong\u003eperfect\u003c\/strong\u003e alignment with each other! This ensures superior bearing performance and less chance of premature wear.\u003c\/p\u003e\n\u003cp\u003e-Hub shell literally “floats” on the axle. The only force on the bearings is supplied by the wave spring(which delivers the appropriate bearing pre-load needed for angular contact bearings). Tightening of axle bolts has absolutely no affect on the bearings!\u003c\/p\u003e\n\u003cp\u003e-The bearings, wave spring, and shim(s) are secured on the axle by one retaining ring. The only tool used to assemble\/disassemble the AC-2 hub is a pair of snap ring pliers!\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e*Profile Racing does offer a simple tool to aid in retaining ring installation and bearing\/cup removal, but is not necessarily needed.*\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e-The AC-2 BMX hub has a true 20mm bolt-on hollow aluminum axle.\u003c\/p\u003e\n\u003cp\u003e-You have a choice of either 10mm socket head(steel or titanium), 10mm button head(steel or titanium), 15mm alum, or 20mm alum bolts when ordering your hub. This hub can be used with any standard chromoly, aluminum, or carbon frame.\u003c\/p\u003e\n\u003cp\u003e-The Profile Racing AC-2 hub is manufactured from a high grade, aerospace quality billet aluminum.\u003c\/p\u003e\n\u003cp\u003e-Front and Rear hubs sold separately.\u003c\/p\u003e\n\u003cp\u003e–\u003cstrong\u003eCeramic Hybrid\u003c\/strong\u003e bearing option available for hub shell bearings.\u003c\/p\u003e\n\u003cp\u003e-Standard BMX 100mm width.\u003c\/p\u003e\n\u003cp\u003e-Made in the USA!\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpoke Holes: \u003c\/strong\u003e28h, 36h\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAnodized Colors:\u003c\/strong\u003e Black, Silver, Red, Blue, Gold, Purple, Green, Matte Black\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBolts: \u003c\/strong\u003e10mm socket head steel, 10mm socket head titanium, 10mm button head steel, 10mm button head titanium, 15mm aluminum, 20mm aluminum\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBearings: \u003c\/strong\u003eSteel 20mm angular contact, Ceramic Hybrid 20mm angular contact\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e 220g\/7.75 oz (weighed w\/20mm bolts)\u003c\/p\u003e","brand":"PROFILE RACING","offers":[{"title":"Default Title","offer_id":67967486165357,"sku":null,"price":169.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0960\/2039\/8445\/files\/AC2-Bmx-Front-Black-e1575312188215-100x100.jpg?v=1794411639","url":"https:\/\/www.staytruebikebarber.com\/products\/ac-2-bmx-front-hub","provider":"Stay True","version":"1.0","type":"link"}
