With an innovative threaded sleeve that connects both bearing shells, this bottom bracket sets new standards in terms of stability and smooth running.\u003c\/p\u003e\n\n \u003cp\u003eThe threaded connection effectively reduces the stresses normally exerted on press-fit sleeves and compensates for dimensional tolerances of the bottom bracket shell. This improves the parallelism of the bearings, resulting in smoother crank running and less noise. External bearing shells also increase the rigidity of the system, while the improved fit protects the bearings from overload and extends their service life.\u003c\/p\u003e\n\n\u003cp\u003e An inner sleeve provides additional protection by protecting cables and electronics from friction with rotating parts. This makes the UBB 4630 bottom bracket not only a technically sophisticated but also a durable solution for your bike.\u003c\/p\u003e\n\n\u003ch3\u003e \u003cstrong\u003eHighlights:\u003c\/strong\u003e\n\u003c\/h3\u003e\n\n\u003cul\u003e\n\n\u003cli\u003e\n\n \u003cstrong\u003eThreaded sleeve:\u003c\/strong\u003e Improves stability and reduces stress in the pressfit system\u003c\/li\u003e\n\n\u003cli\u003e\n\n \u003cstrong\u003ePrecision and durability:\u003c\/strong\u003e Compensates dimensional tolerances of the bottom bracket shell for optimal bearing parallelism\u003c\/li\u003e\n\n\u003cli\u003e \n\u003cstrong\u003eExternal bearing shells:\u003c\/strong\u003e Increase rigidity and ensure efficient power transmission\u003c\/li\u003e\n\n\u003cli\u003e\n\n \u003cstrong\u003eProtection against overload:\u003c\/strong\u003e Better fit protects the bearings and extends their service life\u003c\/li\u003e\n\n\u003cli\u003e\n\n \u003cstrong\u003eCable and electronics protection:\u003c\/strong\u003e Inner sleeve prevents friction with rotating parts\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\n\u003ch3\u003e \u003cstrong\u003eTechnical data:\u003c\/strong\u003e\n\u003c\/h3\u003e\n\n\u003cul\u003e\n\n\u003cli\u003e\n\n \u003cstrong\u003eCompatibility:\u003c\/strong\u003e Only suitable for ROTOR cranks\u003c\/li\u003e\n\n\u003cli\u003e\n\n \u003cstrong\u003eMaterial bearing shells:\u003c\/strong\u003e CNC-machined 7075 aluminum\u003c\/li\u003e\n\n\u003cli\u003e\n\n \u003cstrong\u003eSeals and center sleeve:\u003c\/strong\u003e Silicone\u003c\/li\u003e\n\n\u003cli\u003e\n\n \u003cstrong\u003eBearings:\u003c\/strong\u003e High-quality steel\u003c\/li\u003e\n\n\u003cli\u003e EAN: 8434366006864\u003c\/li\u003e\n\n\u003cli\u003e Manufacturer number: C04-028-01010-0\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\n\u003cp\u003e The \u003cstrong\u003eROTOR UBB 4630 bottom bracket\u003c\/strong\u003e is the ideal choice for riders who value a reliable and durable solution for their Pressfit 30 system.
