They also happened to have a solution for my situation – a PF30-20r bottom bracket that fits perfectly in my frame and at the same time supports my 24mm cranks. They make all kinds of ceramic bicycle bearings including a wide range of BB’s with all kinds of sizes and specifications.
Searching for a better solution I came across a brand called “C-bear”.
I wasn’t happy with that, not to even mention the extra dead weight the adapters bring. Spinning was very stiff because of a lot of drag from using “bearings into bearings” with the adapter. It was working, but the performance wasn’t very good. To use them together first I tried the BB30 adapter that fits in the PF30 Bottom bracket and allows to use the 24mm cranks. I have the new “Thrill Agent” BMX frame with the Press Fit 30mm bottom bracket in it and an Answer Pro crankset with a 24mm spindle. That is a problem I myself had to deal with. Most of the more trusted crank sets in the market (Shimano DXR, Answer Pro cranks, etc…) are still made with a 24 mm spindle. You will not find a lot of cranks in the market with the speciffic 30mm spindle to use for your modern frame. So 30mm BB’s mean all good things, but you can still run into a little problem. The bigger BB also gives room for bigger seat tubes, down tubes and chainstays if needed to produce a stiffer/stronger frame. The 30 mm BB provides more stiffness and strenght for the cranks and the bearings than the more traditional 24mm BB system. More and more modern frames these days are comming out with the modern 30mm Bottom brackets and so is our Thrill Agent BMX Frame. The Thrill Factory Europe Team is stoked to have this brand supporting us.
