BBInfinite makes a very high quality product. I’ve been using them for 2 years now on all my bikes (mountain, CX, road with Shimano, Praxis, and SRAM cranks into Cannondale, Specialized, and Canyon frames) with absolutely no creaks or problems. The silence is nice, but they also work well with the frame to be super stiff and highly efficient - they fit perfectly, remove the inherent problem of aligning bearings/races, the instructions are specific to your frame/crank and are in color, and are easily installed with tools that come with the product. No bushings, no rubber expanders - just machined correctly. If you don’t have a bearing press, they allow you to rent one for like $5 and send it back to them. Their videos are helpful, and it makes intuitive sense.
I have a hard time understanding why more high-level riders/racers aren’t using them. To top it all off, their customer service is super friendly and helpful.
