{"product_id":"ceramicspeed-bb-alpha-bottom-bracket-bbright-shimano-road","title":"CeramicSpeed BB ALPHA Bottom Bracket — BBright Shimano Road","description":"A bottom bracket built to outlast your frame. The CeramicSpeed BB ALPHA adapts a 24 mm Shimano road crank into Cervélo's BBright press-fit shell, delivering the lowest-friction, longest-lasting bottom bracket CeramicSpeed has ever made — so you can keep your Shimano crankset on a wider asymmetric BB.\n\nWhy riders choose BB ALPHA\n\nGrade-3 Silicon Nitride ceramic balls in hardened stainless-steel races. Standard BBright adapters develop drag and creak after a single wet season, so you end up replacing them every year and losing watts in between. The hand-built ceramic bearing system runs ultra-smooth from day one and stays smooth for the life of the frame — you feel less resistance on every pedal stroke and stop budgeting for a yearly bottom bracket swap.\n\nCustom seals with 500% better moisture protection. The wider BBright shell traps moisture more than narrow standards — water gets past the seal and the bearing rusts from the inside. The redesigned BB ALPHA seal blocks moisture and contamination dramatically better than previous generations, so the bearing keeps spinning quiet and free through winter training, gravel detours, and every post-ride hose-down.\n\nSimplified spacer tube + lighter cups, 10% lighter overall. Old-style adapters needed a bag of spacers and a service manual to install correctly into BBright's 79 mm shell, and the cups added grams in the worst place on the bike. The new design installs in minutes with fewer parts to lose, and you save weight right at the bottom of the drivetrain where it matters for acceleration and climbing response.\n\nCustom dust covers refined through 28 design iterations. Cheap dust covers pop loose, rattle, or let dirt in — and BBright shells are notorious for creaking when not perfectly fitted. The fitment-optimized covers stay seated and sealed under real road and race use, so the bearing stays clean and you don't hear any creaks or ticks coming from the BB shell.\n\nLifetime warranty. CeramicSpeed backs every BB ALPHA for life. You install it once and you're done.\n\nWhat's in the box\n• BB ALPHA bottom bracket for BBright press-fit frames, Shimano Road 24 mm\n• UFO TECH All Round Bearing Grease (5 ml)\n• CeramicSpeed decal\n\nFitment\nBB shell: BBright (42 mm ID × 79 mm wide, press fit, asymmetric)\nCrank axle: 24 mm (Shimano road and compatible 24 mm cranks)\nDiscipline: Road, Tri\nNet weight: 92 g\n\nBBright is Cervélo's wider asymmetric press-fit standard, found on most modern Cervélo road and tri frames (S5, R5, P5, Caledonia, Áspero). If your frame is a Cervélo from the last decade, BBright is almost certainly your shell.","brand":"CeramicSpeed","offers":[{"title":"Default Title","offer_id":53441097105751,"sku":"CS-BBALPHA-BBR-SHI-ROAD","price":389.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0756\/5403\/7847\/files\/bbright.png?v=1777528326","url":"https:\/\/shop.approvedcycling.com\/sl\/products\/ceramicspeed-bb-alpha-bottom-bracket-bbright-shimano-road","provider":"Approved Cycling","version":"1.0","type":"link"}
