BBInfinite T47 Design Philosophy Explained: Kudos to Chris King

BBInfinite T47 Design Philosophy Explained: Kudos to Chris King

December 28, 2022

 

We pioneered and perfected the 1-piece, hub style PressFit years ago that solved creaking issues and transformed the lowly bottom bracket into a legitimate performance part that went from optional to absolute necessity in every cyclist's performance arsenal. The advent and widespread adoption of T47 is a welcome addition to the bottom bracket universe---thank you Chris King---that has allowed BBInfinite to work our magic without the constraints associated with the PressFit format. This video explains why T47 just may be the best thing to happen to bottom brackets in our lifetimes.

I want to talk to you guys a little bit about T47 right now this is more of a philosophical video on our design philosophy surrounding this product so if you'll go ahead and come on in here you'll see that T47 is of course threaded ours has a Delrin ring on one side and as compared to a traditional press fit which is totally smooth and it gets pressed in now where this is where this is advantageous the reason that the threads are advantageous on this a lot of people are just thinking about retention you know when it screws in it's not going to creak and all that sort of thing we already solved creaking problems with PressFit with it being a one piece the advantage to threads on this has nothing to do with retention and it has nothing to do with whether or not it's going to creak okay what is the advantage here is this right there how loose it fits believe it or not I'm going to go ahead and thread this in right now and this is a thread standard this is exactly how it would be in your bike this be bonded in there and i want you to check this out hear that noise right there that's this wiggling okay because this is threaded in order for it to be able to thread it naturally has to have some play in it or else you'll never be able to thread it in because the friction isn't coming from the press fit the friction is coming from the action of the threads against the threads so why is this important well because it doesn't give us a problem as far as the bearing fit we're not in control of the of the inner diameter of the bike frame we're pressing this into and sometimes that can be a problem it can be excessively tight okay and then it will have you see how thin that is that could actually have a lot of influence on the way the bearing performs because it will do what's called radial compression on the bearing with T47 that is not a problem because of that looseness I showed you it's not constraining the outside the outer diameter of the BBInfinite module at all and it's allowing us to really dial in the bearing performance the way we want and that's why we end up with spin like this every time with T47

Also in BBInfinite exists to elevate the bottom bracket to the high-performance, low-maintenance, reliable component it is meant to be. Rid yourself of press fit bottom bracket creaks and pops. BBInfinite is silent performance.
