So I bought a new road bike after many years and I know nothing of the new BB/Crankset standards. It is setup with Pressfit 30 and Force compact 2012 (I guess) crankset. I wanted to get ready to maintain it so was looking into how to pull the cranks. But looking around SRAM's site I see nothing that matches my cranks. My cranks have a 10mm hex fixing bolt on the left side. It appears to be captive by a threaded ring that is installed by a pin spanner. I don't see anything like that on SRAM, but I see a number of examples for sale on e-bay, so I'm guessing this is an OEM setup that SRAM doesn't advertise?

It seems pretty obvious just to remove the 10mm bolt and the left side should pop off and then just pull the right side spindle and crank as a unit. But I am wondering how to properly install. I see reference to "preload adjuster" but from looking at it I don't see anything like that. I don't really want to pull it until I know I can get it back together correctly (only have a few 100 miles on the bike and don't really want to mess it up).

I see many references to SRAM GXP but is that mtb only, or if not is a SRAM GXP crankset compatible at all with Pressfit 30? I guess I don't get the whole deal with "wavy washers", spacers, etc. I'm used to square taper -- just install the cranks and go.

Thanks (for reading and any knowledge you can impart)
