SRAM® PressFit 30™ (PF30) bottom brackets have been designed and tested to work within the bounds of the dimensions and tolerances in the shell specifications and bottom bracket specifications. Materials, manufacturing methods, and frame shell designs can potentially influence the performance of the bottom bracket, even when the shell is manufactured to these specifications. In these instances, it is recommended that bicycle manufacturers confirm the bottom bracket system performance with individual frame configurations.
Things that should be considered when evaluating the frame and bottom bracket interaction include, but are not limited to:• Loosening of the adapter cups from the bottom
bracket shell (frame material choice can greatly affect friction coefficient).
• Binding of bearings within the bottom bracket.
