Comments about Problem Solvers PF30 / BB30 Adapter:
These adapters fit nicely into my BB30 press-in bearings, and installation was a snap.
Unfortunately, my Race Face crankset did not fit easily into the adapter holes. I had to coax the crank spindle in using a rubber mallet, but the fit was too tight to actually work properly. Trying to get the spindle through the adapters resulted in the opposite side bearing coming out with the adapter!
Furthermore, the chain line would not work out even when I managed to get the crankset forced in. I think the overall width is insufficient for Race Face cranks, even when stacking a bunch of spacers.
So, avoid this product if you're trying to move a Race Face crankset over! Stick with the Race Face branded product instead, because it fits perfectly…
(Note: The Jenson and Problem Solvers sites list the adapter as compatible with Race Face X-Type cranks. This is not the case!!)
