This is the pressfit variant sized for MTB121 shells, making it the right choice for fat bike frames with 121mm bottom bracket shells.\u003c\/p\u003e\n\n\u003cp\u003eDUB — Durable Unified Bottom Bracket — was developed so that a single crank platform could span the full range of frame standards on the market. The larger spindle diameter means the bearings run against a bigger surface, which reduces the load per unit of contact and extends service life under the kind of torque that mountain riding generates. Installation follows standard pressfit procedure, and the bearing cups are designed to seat cleanly in a properly faced shell.\u003c\/p\u003e\n\n\u003ch3\u003eSRAM DUB Pressfit MTB121 Bottom Bracket Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBottom bracket standard:\u003c\/strong\u003e Pressfit MTB121 (121mm shell — fat bike)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpindle diameter:\u003c\/strong\u003e 28.99mm (DUB standard)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e SRAM DUB cranksets\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSKU:\u003c\/strong\u003e 00.6418.016.001\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"SRAM","offers":[{"title":"Default Title","offer_id":43705706283052,"sku":"00.6418.016.001","price":55.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/ricycles.com\/products\/sram-dub-pressfit-mtb121-bottom-bracket","provider":"RA Cycles","version":"1.0","type":"link"}
