Bottom Bracket Selection Guide
BBInfinite T47 Internal and External 1-Piece, Hub-Style BB's for 30mm, DUB, Shimano, Gxp, and M30
T47 comes in two main varieties: internal and external. All the new Treks, for instance, are the internal type, which means the entire bottom bracket resides within the bike frame with just the flanges showing from the outside, kinda like a threaded version of BB386Evo, if that helps. The external type is based on the good old 68mm wide bottom bracket shell, and once installed looks like a giant Shimano Hollowtech2 bottom bracket, with what looks like cups sticking out about 10mm on each side of the frame bottom bracket shell. There's one called BBcorrect, which is a variant of the internal type that's only found in the Factor OSTRO VAM----and we have it! ----but let's just skip that for now. This being the bike business there are sure to be many variations from here as T47 slowly becomes the dominant bottom bracket standard throughout the industry, but for now these are the main types. We've got them for every popular crank type except Campagnolo UltraTorque. Should we make it? Let us know. Here's a T47 install vid for you to check out: T47i Install
Trek has gone all in on T47 and BBInfinite has brought our one piece technology to T47 let me show you what we got right here is a T47 internal version on both of these this one right here will be either Shimano or GXP with a simple hardware change same thing down here with a simple hardware change you can run the ever popular DUB 30mm spindle or you can run a Praxis M30 shift over here and you will see the external version which you will see these logos outside because this is based on a 68mm wide bottom bracket shell of course same thing as over here all one piece and will run the same crank set so what we have here is we have one piece hub style bottom brackets from BBInfinite for Shimano crank for GXP for 30mm spindle DUB praxis M30 and it's all BBInfinite
