Anybody got any experience with the Real World Cycling press fit bottom bracket replacement for Hifi's (i.e., BB 91-41)? My OE Shimano BB is still going strong since 2010 however the last time I pulled the cranks for some cleaning I noticed that the outer plastic drive side flange on the BB has broken. It has not caused any performance issues, but I want to replace it before it does become a problem. RWC makes an aluminum replacement for not much more than the plastic body OE Shimano, but I was hoping for some experienced input before I buy it. That or suggestions otherwise. Thanks for any assistance.
