{"product_id":"sram-force-1-bb30-crankset","title":"SRAM Force 1 BB30 Crankset","description":"\u003cp\u003eSRAM’s  Force 1 Crankset is the way to start building your 1x drivetrain.\u003c\/p\u003e\n\u003cp\u003eThe Force  Crank here is the same crank you’ll find on 2x systems. It features  carbon-fiber arms and an aluminum spider where the fifth arm is actually the  right crank, with one of the chainring bolts threading into to the crank. You  get lightweight with carbon, and superb stiffness with chainring and spider working  together. \u003c\/p\u003e\n\u003cp\u003eThe  stiffness is enhanced, and the chain is secured thanks to the X-SYNC Chainring.  You may think that single-ring setups just take one ring from a double-ring  crank and that you’ll need a chain guide to keep the chain on the ring. With X-SYNC,  there’s no need for any secondary retention system. The key is a unique tooth  profile. The teeth themselves are taller than you’ll find on shiftable chainrings.  The tops of these teeth are also squared, rather than triangular. And then SRAM  goes farther. The base of the teeth has been engineered to possess mud-clearing  recesses. They created a unique wide-narrow alternating tooth pattern which  lines up with the inner and outer cage plates on the chain.\u003c\/p\u003e\n\u003cp\u003eThe tooth  pattern synchronizes with the chain. They recommend their standard eleven- and  ten-speed chains. The chainring teeth and recesses have been designed with this  chain in mind.\u003c\/p\u003e\n\u003cp\u003eSRAM  offers two different bolt circle diameters, 110mm and 130mm. The 110 works with  X-SYNC chainrings of 38, 40, 42, 44, 46, 48, and 50 teeth. The 130 works with  52 and 54 teeth. The single chainring is offset toward the bottom bracket,  which is another difference between a ring designed for front derailleurs. Keep  in mind, that with this crankset you are not forced to keep it 1x. You can pull  the X-SYNC ring and install a double-ring setup so long as the chainrings match  the bolt circle diameter you’ve already chosen.\u003c\/p\u003e\n\u003cp\u003eCrankarms  can be as short as 162.5mm and as long as 177.5mm.\u003c\/p\u003e\n\u003cp\u003eThe bottom bracket is not included, so you can choose what works best  for your needs. The cranks come with a thru-axle, which can be either a GXP,  the traditional 24\/22mm SRAM bottom bracket spindle, or a BB30. The GXP version  mates to English- or Italian-threaded GXP bottom brackets or with adapters to  most bottom bracket standards (BB30, PF30, BBright, BB86, BB386EVO, BB47). The  BB30 spindle works with BB30 and PF30 standards and can, in some cases, be  mated to an external bottom bracket as well. \u003c\/p\u003e\n\u003cp\u003eThe SRAM Force 1 Crankset weighs 679g when configured with 172.5mm  arms, a GXP bottom bracket, and 50-tooth chainrings. It’s the heart of a great  1x system.\u003c\/p\u003e","brand":"SRAM","offers":[{"title":"52t \/ Black \/ 170mm","offer_id":43520989331500,"sku":"00.6118.367.001","price":129.99,"currency_code":"USD","in_stock":false},{"title":"52t \/ Black \/ 172.5mm","offer_id":43520989364268,"sku":"00.6118.367.002","price":129.99,"currency_code":"USD","in_stock":false},{"title":"52t \/ Black \/ 175mm","offer_id":43520989397036,"sku":"00.6118.367.003","price":129.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/sram-force-1-bb30-crankset-9946040.jpg?v=1771296909","url":"https:\/\/ricycles.com\/products\/sram-force-1-bb30-crankset","provider":"RA Cycles","version":"1.0","type":"link"}
