Hi Everyone,
I bought a new crankset to replace the one in my bike.

Old one is FSA triple compact with megaexo BB.

Looks Like it should be pretty straight forward swap🙄 any little things I should be aware of before I start? Do I need to go to a double FD or can I adjust the limit on the triple?

Thanks for any help.

Grease the BB shell, cups and spindle. A wee bit of the supplied locktite on the splines after cleaning them. Lower FD, it should work fine with a double. Remember it shifted middle to big before, it will work with 2 rings instead of 3. 'May' need to take a link outta the chain depending on how well it was sized before, assuming you have a long or mid cage RD.

Both large chain rings are 50 and I think I am going to swap the 39 from the old one to replace the 34 on the new one, (not to many hills in N.E. Ohio) will I still need to lower the FD?
