Removing a Bonded BB Cup System
Currently, the bearings of most Pressfit 30 BB cup systems are not replacable and are not
intended to be removed from the cups. In order to replace bottom bracket bearings, the
complete BB cups system (cup w/bearing installed by manufacturer) must be replaced as a new unit.
Residual Loctite (green in color) may or may not be visible around the cup edges as an indication that the cups Pressfit BB30 frame have been bonded. So, exercise patience when attempting to remove any cup system. The tools and methods for removal will vary by manufacturer, so be sure to follow instructions provided.
A nylon BB cup system by SRAM is shown throughout these instructions. With this system, when bonded, we have found that it is necessary to first carefully drive the bearing out of the BB cup. Then, the BB cup can be easily driven out with Park Tool RT-1.
Disassembly instructions for Loctite 609 product instructions indicate heatings parts prior to disassembly. We have found that heating is NOT necessary in this application and recommend that you do not do it. Excessive heat can damage the paint and destroy the carbon frame.
I don't, I've never had issues with stock BB30 / PF30 setups but I read some very good reviews of the Enduro TorqueTite PF30 XD15 though. It's not cheap so it's worth researching if it really is good...Thanks both MMsRepBike and Dan for some great advice !!!
I will go with the Wheels Manufacturing BB.
Now i have to decide Angular Contact bearings or regular.
Dan, do you have an actual experience with both ?
I read some mixed reviews about the ACB
