SRAM's Gutter Seal Technology drastically improves sealing against water and grit, extending bearing life and keeping rotational friction low. Whether you're running an older GXP crankset or the newer DUB standard, the matching SRAM BSA bottom bracket delivers a guaranteed-fit interface. DUB variants are significantly lighter than the GXP system that came before.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eConstruction \u0026amp; Materials\u003c\/strong\u003e\u003cbr\u003e\nLightweight aluminium cups thread directly into the BSA shell, housing sealed cartridge bearings inside SRAM's Gutter Seal Technology design. The seal architecture is the same one SRAM uses across its premium drivetrain components, prioritising water and contamination resistance without adding friction.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCompatibility\u003c\/strong\u003e\u003cbr\u003e\nFits any BSA English-threaded frameset. Three variant options cover the SRAM crank range: SRAM GXP (24mm spindle, 73\/68 shell, road chainline), SRAM DUB Standard (28.99mm spindle, 68-73mm shell, suitable for road or MTB chainlines), and SRAM DUB Road Wide (28.99mm spindle, 68mm shell, 47.5mm road chainline). DUB Road Wide is the right choice if your drivetrain runs a 1x setup with a wide-range cassette, where the extra chainline clearance protects against cross-chain rub on the largest cogs. Select the variant that matches your crankset and chainline requirement.\u003c\/p\u003e","brand":"SRAM","offers":[{"title":"28.99mm - SRAM DUB (Road Wide) \/ Black","offer_id":54293057601882,"sku":"1390753","price":30.0,"currency_code":"GBP","in_stock":true},{"title":"28.99mm - SRAM DUB (Standard) \/ Black","offer_id":54293057634650,"sku":"1081283","price":30.0,"currency_code":"GBP","in_stock":true},{"title":"24mm - SRAM GXP \/ Grey","offer_id":54293057667418,"sku":"114969","price":38.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0956\/0827\/5290\/files\/SRAM-SRAM-Bottom-Bracket-BSA.jpg?v=1781186704","url":"https:\/\/checkout.sigmasports.com\/products\/bottom-bracket-bsa-17tpf","provider":"Sigma Sports","version":"1.0","type":"link"}
