Okay so this frame (my wifes), is a Ceepo Viper-R. BB3886evo. The press fit cups that were included were these: FSA PF30 BB
. The adapters are these: FSA BB3886evo to GXP
. It's that little plastic rim that interferes with the Riken and as far as I can tell that is part of the actual BB and can't be removed.
Here are some greasy pictures of both sides of the BB area
. I'm aware that seal thing is cracked and also the NDS picture might not be showing up.
It definitely seems like the bbinfinite option is best, except for the fact that they only have the expensive one in stock and we are seriously penny pinching right now. But considering the other option is just upgrading to a Dzero Spider or a brand new 30mm dzero it seems like it may be worth it.
The BB photos wouldn't come up in Google Photos, but your links explained how you tried to setup the frame.
The terminology with press fit bottom brackets can be confusing. That Ceepo frame has a 46mm BB shell diameter. Pressfit bottom bracket cups are pressed directly into the carbon frame shell. These cups hold sealed cartridge bearings. The combination of the cups and the bearings is the "bottom bracket." As I mentioned earlier all these 30mm PF BB standards have the same cups and bearings. They just differ in installed width depending on what BB standard of frame they are pressed into.
The plastic PF cups are removable and meant to be discarded after removal. They are usually damaged during removal anyway. These are what I mentioned earlier as what are knocked out with a headset cup removal tool. You can see the shell w/o any cups in the photos here: https://trieverythingstore.com/...athlon-bike-frameset
You mentioned you didn't have PF BB tools so it is probably easiest to have the shop that installed it knock it back out. This example is a smaller diameter PF BB, but it shows you what I'm describing. https://www.youtube.com/watch?v=yOJAKBQOU9U
That's too bad that BBInfinite is out of stock on the steel bearings. It might be worth dropping them and email or calling to see if they can get you the steel bearing version in the short term.
Yeah. Tough call on upgrading to DZero spider or crankset at $680+ vs. new BB:(
