Park Tool RC-1 Press Fit Retaining Compound for Bicycles

This is excellent for coding the two surfaces that need to be press fit together. In my case, it was a vintage American bottom bracket on a 1983 profile champ pro frame and I also used it on the headset when I pressed in an OG HATTA headset

Used product for bonding of bike press fit Bottom Bracket.

Used this to install a pf92 bottom bracket. Applied primer to the carbon shell and then the retaining compound. Creak free so far.

If your goal is to bond your bottom bracket in so tightly you can't remove it, this seems to do the trick. I applied the Park Tool Primer liberally and made sure to put it on a larger area than the bottom bracket could contact. In theory if you use Park Retaining compound this will prevent adhesion, but in my aluminum sleeve it did not. Bottom brackets which could be removed with a rocket tool will no longer come out that way anymore. You'll have to try cutting the bottom bracket with a hack saw or some such and then chisel, grind, or drill it out in sections, likely damaging the bottom bracket sleeve in the process. The good news is that there is no way your bottom bracket will make creaking noises at least for awhile. Hope it breaks free before the new bearings are shot.

Quick, easy, and effective. FYI, I used it when installing BB92 press fit on a steel frame fat bike.

Great stuff

The product worked perfectly to quiet a bottom bracket which has plagued me for years. I tried a wheels manufacturing screw together (which still didn't work), but the retaining compound did its job. My press fit shell was also quite worn, and I could press in my bearings by hand. UPDATE: After about 2 days since the application all of the creaking returned to the BB. Seems like the product works, but there is some limit. Some issues might just require a new frame is the bottom bracket shell is worn enough.

Back of packaging says competes with loctite 680.
