{"product_id":"box-one-quantum-20mm-cassette-hubset","title":"Box One Quantum 20MM Cassette Hubset","description":"\u003cp\u003eFor more than seven years, Box Founder Toby Henderson has been trying to build a reliable 20-mil, rear, cassette hub without creating a new cassette standard. The problem was fitting durable bearings between the cassette body and the oversize axle. The rear Quantum hub overcomes this dilemma by using the type of one-piece driver commonly found on “freestyle” hubs. Each hub set includes a one-piece, 16-tooth driver supported by three large, roller bearings. Inside the driver are six pawls, each with two teeth that engage a 60-tooth ratchet ring, meaning the hub has just 6 degrees of engagement. The end result is a higher performing hub with fewer dead spots and less drag than others on the market. Quantum front hubs are available only with 20-mil axles, but the rears can be easily converted between 10-, 15 and 20-mil axles. Each set includes a front and rear 20-mil set-up. Additional spacers included. Optional 10- and 15-mil axles are sold separately.\u003c\/p\u003e","brand":"Fluxx BMX","offers":[{"title":"Black","offer_id":45061668143173,"sku":"355473J","price":349.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/0479\/7509\/files\/original_91cd2828-6b49-4b5d-a5a4-a45d01f34737.jpg?v=1779908938","url":"https:\/\/fluxxbmx.com\/products\/box-one-quantum-20mm-cassette-hubset","provider":"Fluxx BMX","version":"1.0","type":"link"}
