The T47-86mm 3-in-1 uses a T47 threaded shell interface with a set of swappable inner cores and end caps, so the same shell can accept all three spindle standards.\u003c\/p\u003e\u003cp\u003eWhat's actually equipped is a pair of Tripeak's own G5-grade ceramic bearings, running in an Alloy 6061 cup with a glass-fibre-reinforced polyamide (PA+GF) sleeve, plus the core and cap set for 24mm (Shimano HollowTech II), 28.99mm (SRAM DUB), and 30mm (ROTOR 3D+) spindles. T47's larger 47mm shell diameter gives the bearings a wider stance than a standard threaded 68mm shell, which is the main reason T47 frames use it in the first place - more support under the bearing means less flex through the cranks.\u003c\/p\u003e\u003cp\u003eIn practice, this is the bottom bracket to reach for on a T47-shell frame you expect to keep building on: swap a crankset later and the shell stays exactly as it is, only the core changes.\u003c\/p\u003e\u003ch5\u003eWhy You'll Like It\u003c\/h5\u003e\u003cp\u003e\u003cstrong\u003eOne shell, three crank standards\u003c\/strong\u003e: swap between Shimano HollowTech II, SRAM DUB, and ROTOR 3D+ cranks on the same bottom bracket by changing the core and caps, instead of buying a new unit for every crank standard.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCeramic-grade smoothness\u003c\/strong\u003e: the G5 bearing grade is Tripeak's ceramic-ball spec, built to spin with less friction than their steel P05 equivalent.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDurable cup construction\u003c\/strong\u003e: an Alloy 6061 cup paired with a glass-fibre-reinforced polyamide (PA+GF) sleeve is built to handle a T47 shell's daily load without excess weight.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eA wider bearing stance\u003c\/strong\u003e: T47's 47mm shell diameter supports the bearings more evenly than a narrower threaded shell, which is part of why modern gravel and all-road frames are increasingly speccing it.\u003c\/p\u003e\u003ch5\u003eWho Is It For?\u003c\/h5\u003e\u003cp\u003eRiders on a T47-shell frame - increasingly common on modern gravel and all-road bikes - who want a bottom bracket that won't limit which crankset they can run down the line. If your frame takes a T47 threaded shell, this is the straightforward upgrade over a stock bearing.\u003c\/p\u003e\u003cp\u003eIt also suits BOTS customers building up a frame from scratch or swapping groupsets, where not knowing your next crankset in advance is normal - the core-swap system means that decision doesn't have to be made twice.\u003c\/p\u003e\u003ch5\u003eGood to Know\u003c\/h5\u003e\u003cul\u003e\n\u003cli\u003eFit the core and cap set that matches your crank's spindle diameter (24mm, 28.99mm, or 30mm) before installing.\u003c\/li\u003e\n\u003cli\u003eKeep the T47 threads clean and lightly greased for a smooth, quiet install.\u003c\/li\u003e\n\u003cli\u003eWipe the shell down after wet rides to keep the threads and bearing seals in good condition.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch5\u003eTechnical Specifications\u003c\/h5\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBottom Bracket Type\u003c\/strong\u003e: T47, threaded, external bearing cups\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBearing Type\u003c\/strong\u003e: Ceramic (Tripeak G5 grade)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: T47\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShell Width\u003c\/strong\u003e: 86mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpindle Compatibility\u003c\/strong\u003e: 24mm (Shimano HollowTech II) \/ 28.99mm (SRAM DUB) \/ 30mm (ROTOR 3D+), via swappable cores and caps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBearing Set Weight\u003c\/strong\u003e: 74g (per set, without end caps)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCup Material\u003c\/strong\u003e: Alloy 6061\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSleeve Material\u003c\/strong\u003e: PA+GF (glass-fibre-reinforced polyamide)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColour\u003c\/strong\u003e: Gold\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch5\u003eAdditional Information\u003c\/h5\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: Taiwan\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImported By\u003c\/strong\u003e: We Snap India, M.
