THIS IS A CNC MACHINED BOTTOM BRACKET, but is undersize on the inside diameter and will require reaming after welding
The inside diameter is precision turned and undersize in the middle for lighter weight. Inside diameter is 45.4mm on bearing surface with a 12mm depth before undercut. O.D. is 52.5mm and has reinforcing rings with OD 54mm to help with keeping roundness when welding.
This model has no holes, and receives a fine machined finish.
