congrats on having no issues with mounting your setup.
on the SL4, i had a compact srm on a specialized crank. the compact srm may have a slightly smaller ID for the relief around the bb shell.
the reason you could not use the sram pf30 bb with your setup is you only tried mounting it with the srm bearing shield. you would most likely have been able to use it if you either:
removed the supplemental seal over the left bearing, or
used the sram-provided bearing shields on both sides.
the sram bearing shields have a larger relief under it to clear their seals.

Possibly, but I spent a number of hours trying all possible combinations of shields/seals/spacers/spindles with marginal results yet swapping out the SRAM PF30 for the FSA PF30 worked with the SRM bearing shield, SRM spindle, and 3 spacers.thisisatest wrote:ms6073,

Having ordered the Cannondale KP197/SRM PF30 bottom bracket kit, I will find out how well it works this weekend now that I have a can of the Loctite primer to go with the Loctitte 609. Interesting to note that Cannondale's bonding instructions supplied with the bottom bracket kit outline installation for a SRAM PF30 bottom bracket and not the Cannondale specific parts. This has me wondering after I bond/press in the alloy press-fit shell cups, do I then repeat the process of applying Loctite Primer & 609 Retaining Fluid to the inner races of the alloy shell and the outer part of the bearings before pressing them in? I am guessing the answer would be yes in order to avoid creaking like with the BB30 bottom brackets.
personally, i still wish it was BB30, but PF30 is easier to manufacture for everyone else due to more open tolerances.
Out of the box with no modifications, no. I think you will find that it is possible if you order the new SISL2 spindle (KP248). Alternately, you could locate a local machinist to modify your existing spindle to remove the shoulder as discussed here.skinnyrider wrote:Is it possible to fit the older, non bevel SRM to a pf30 Evo frame?
