{"title":"Hubs","description":"\u003cp\u003e This is a bicycle wheel component that rotates on an axle attached to the frame. There are several standards for this type of mounting. The simplest method is to secure the hub axle with standard nuts. This type of mounting requires the use of a suitable wrench to loosen and re-tighten the wheel each time. For many years, hubs with a quick-release mechanism were the standard. For several years now, the dominant and undisputedly best solution has been thru-axles, which provide significantly improved wheel and frame stiffness, as well as more reliable, repeatable assembly without the need to adjust the brake caliper after removing the wheel.\u003c\/p\u003e\n\n \u003cp\u003eBoth hubs in a bicycle are designed as sleeves containing bearings. The sleeves are usually made of aluminum. Ball or cartridge bearings are encased within them. The latter offer a much longer service life but are also noticeably more expensive. The sleeves have two flanges with holes for mounting the spokes. In the simplest bicycle setup (fixed gear), both hubs function exactly the same. However, the rear hub usually has a freewheel (threaded hubs onto which the sprockets are screwed). Alternatively, rear hubs can have planetary gears (e.g., Shimano Nexus, Sram Automatix). Some rear hubs, instead of a freewheel mechanism, have a so-called coaster brake—a type of hub equipped with a braking system activated by pedaling movement opposite to the bicycle's power. Front hubs with a built-in dynamo are less common, allowing them to power bicycle lights.\u003c\/p\u003e\n\n \u003cp\u003eDemountable hubs require regular inspections, including disassembly, bearing wear assessment, and lubrication. Non-demountable hubs also require occasional adjustment. Adjustment is performed using locknuts, which adjust the ball pressure on the races. Too much pressure causes the hub to rotate too slowly, while too little causes play.\u003c\/p\u003e","products":[{"product_id":"piasta-novatec-nt-a185sbt-tor-przednia-wysoki-kolnierz-light-32h-srebrna","title":"Novatec NT-A185SBT front track hub high flange (Light) 32H - silver","description":"\u003cp\u003e Body: Aluminum\u003cbr\u003e\n Designed for track bikes.\u003cbr\u003e\n Axle: CrMo M9x140mm for nuts.\u003cbr\u003e\n Wheelbase: 100mm.\u003cbr\u003e\n 2 sealed bearings (CH).\u003cbr\u003e\n WEIGHT: 172 grams.\u003c\/p\u003e\n\n","brand":"Novatec","offers":[{"title":"Default Title","offer_id":43365430788233,"sku":"","price":170.0,"currency_code":"PLN","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0669\/0547\/3161\/files\/piasta-novatec-lekka-Sredni_d89ecd45-bdc4-476c-8096-9242829d5dc5.jpg?v=1739730853"},{"product_id":"piasta-gran-compe-niski-kolnierz-przednia-32h-czarna","title":"Gran Compe Low Flange Front Hub 32H - Black","description":"\u003cp\u003e Weight: 176 g\u003cbr\u003e\n body made of cold forged aluminum\u003cbr\u003e\n Sealed cartridge bearings\u003cbr\u003e\n Holes: 32\u003cbr\u003e\n Spacing: 100 mm\u003cbr\u003e\n hub flange height 47mm\u003c\/p\u003e\n\n","brand":"DIA COMPE","offers":[{"title":"Default Title","offer_id":43365431378057,"sku":"","price":259.0,"currency_code":"PLN","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0669\/0547\/3161\/files\/piasta-gran-compe-sf-przod-czarna.jpg?v=1739730924"},{"product_id":"piasta-dia-compe-przednia-32h-niebieska","title":"Dia Compe front hub 32H - blue","description":"\u003cp\u003e • Cold forged aluminum hub body\u003cbr\u003e\n • Sealed cartridge bearing\u003cbr\u003e\n • Front: 32H\u003cbr\u003e\n • 100 mm wheelbase\u003cbr\u003e\n • Weight 280 g\u003c\/p\u003e\n\n","brand":"DIA COMPE","offers":[{"title":"Default Title","offer_id":43365431410825,"sku":"","price":180.0,"currency_code":"PLN","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0669\/0547\/3161\/files\/piasta_diacompe_p_32_nieb-3.jpg?v=1739730929"},{"product_id":"komplet-piast-maszynowych-antymateria-36h-srebrne","title":"Antymateria 36H Machine Hub Set - Silver","description":"\u003cp\u003e A complete set of hubs with cartridge bearings.
