Choosing a centre can be a nightmare for the uninitiated. In the next few lines we'll simplify things and explain how to choose the right centre for your bike and cranks in our shop.
Click on the "center compositions" in our "POHON" category.
A bunch of Praxis and Acros brand centers will expand.
Now you are looking for the right one for your cranks, as there are different axle diameters across manufacturers.
For example, do you have Shimano brand cranks?
Click in the filter on the left.

The filter will only expand the centres for Shimano cranks. That solves the axle type.
Now it's your turn to choose the bearing (centre) seating in your bike frame, which again varies across bike manufacturers.
What brand is your bike? What type? Better yet - what model year? Use google - look up what centre is in your bike by make and model. And if you have no idea "which one beats" - feel free to give us a call, we can help!
Depending on what you've found your bike to have for a center - type in the abbreviation that indicates the center fit in your frame (BSA, BB, ...... there are many) and click in the filter on the left.

Done!
What came up is what you are looking for :).
Both the American brand Praxis and the German brand Acros make top quality centers!
