In this vid we're removing a BBInfinite DirectFit GXP One-Piece bottom bracket to make way for a Rotor 2in-Power crank, and boy-oh-boy this sucker was stubborn coming out! This situation was due to the frame being way too tight to begin with, which is a problem we'll solve in Vid-2. We're very glad to bring this true-to-life content to you. We want you guys to see this real-life process from start to finish so you can be informed and ready to handle any situation that arises, because working on your bike should be enjoyable and fulfilling, and not a PTSD-inducing nightmare. Keep an eye out for Vids 2, 3, and 4 in this series.
This super caliber came in from the wild and it has a GXP crank in it and we want to put this 30mm in power crank in there now a GXP or a Shimano bottom bracket cannot be converted to 30mm or DUB because this has right now in it a BBInfinite module for GXP so I'm going to go ahead and take this byte that just came in and I got to remove this module put in a new one that will work with this so let's do that right now so I've removed the crank and now I've installed our mts1 which is also a bearing press and what I'm doing is I'm taking this wrench and I'm tightening the dies against the module so that this thing is in there really solid like that all right so now I'm going to be in the way for a second all right so right now I want to I'm going to just tee up on this thing I'm going to get a good whack all right so I want to brace the frame sometimes you're going to have to have somebody come and embrace the frame over here I'm just going to go ahead and see about doing this one on my own okay you can see it's already started to move a little bit very little so these are really in there you see it's starting to move now I am really having to give this the beans right to really hit it to knock it out of here I got it this far right here I was really wailing on it okay I'm trying to spare you guys from hearing all that beating but I want you to see that you really do have to hit it hard okay now this isn't gonna break anything unless you slip and smash your hand that will break your hand or if you slip and hit the frame you will break the frame but I mean just by hitting it like this this frame is dissipating so much of that energy so one of the things about carbon fiber is that it dissipates a lot of the energy that I'm putting into it right now all right as I'm going occasionally I will come in here and I will tighten up the dies on the module so this thing is not moving around in here okay because uh we want to make sure that we're coming out straight which we are and when it gets down to the wire here where it's just about to pop out you this thing could launch across the anybody who's ever removed any bottom bracket before knows you can send pieces flying so always be cognizant of everything that's downrange at this point because [Music] [Music] because you don't want it flying all the way out so i had to wallop the crud out of this thing to get it out of this bike of course the bike is not hurt at all everything is fine 100 there no problems these structures are incredibly strong and once again because the carbon fiber dissipates so much of the energy of every hammer blow you really have to put a lot into it a lot of arm and also i can tell by just as i'm removing this that this is going to have to be reamed out because this bottom bracket shell was excessively tight when this was installed so all those factors combined mean you have to really wallet these things to get them out but once again it's just required and eventually it'll come out
