Drivetrain conversion
I have a 2015 Orbea Alma H70 29er and I'm switching to a 2x10 from a 3x10. My Question is can I use my existing cassette and just switch out the crankset for a 2x and do I need to change bottom bracket as well?

I can't think of a reason to change your cassette unless it's worn and won't work with your new chain. The bottom bracket depends on the crank. Your new crank may or may not be compatible with what you have, check the specs.

Agreed with the cassette remaining the same but for the gear ratio changes that will be with a 2x. Will the new set up with the old cassette do what you need ratio wise? Andy
