Question about Cranks to the Mechanically Inclined

Does the Praxis Alba Crank work with Shimano 105 Groupset?
I am doing some upgrades on a bike and I know it is important for certain parts to work together..
I am going from a 3x9 to a 2x11 drivetrain

The specs say it works with both 10 and 11spd chains specifically so it will be fine.

Their webpage for the Alba Crank also states ''SHIMANO — Praxis rings shift great with both Di2 and mechanical Shimano 10/11sp drivetrains''

bottom bracket compatibility could be the fly in the ointment just make sure your frame can accept whatever the praxis cranks bb is.

make sure you order correct BB; it is proprietary

I am not sure, and some one will correct if I am wrong, but I believe going from a 3 FD to a 2 FD the chain line will have to be corrected. That would be when installing the BB. Please anyone, right or wrong?

some one mechanically inclined should understand this

It would be a good practice to check, certainly. However, if the new double crank and bottom bracket are designed to go together, it’s pretty likely that the chainline will be good as installed.

Yea I thought that might be a sticking point. I will reach out to Praxis and Giant to make sure one of their BB will mount up to my frame.. I see no reason why one wouldn't but It is always good to check and find out so I don't order the wrong one.

Of course.. when I go from a 9 speed to 11 speed I will have to buy an 11 speed chain, that won't be an issue.

I was more concerned about a Shimano 105 front Derailleur being compatible with the Praxis Crank and as above.. Which Bottom Bracket would mount up to my frame correctly.

With Bike Mechanics, I am a Noob and not as mechanically inclined. I heard about chain widths with the diff sized chains.
But have no experience with actually comparing them or lengths.
Once I understand more and more about bike mechanics by continuing to work on them.. I will get more and more adept.. not there yet haha

Funny enough I do have a few books in my saved for later on amazon to help me here.

But because I didn't know, I thought I would ask here to those more knowledgeable than I am
