Good morning everyone!

so im finally getting my first bike! before you all get too excited its nothing magnificent. its just a run of the mill bike my dad no longer uses and wants out of his house. the brand is a CCM X-Volt. (it'll do for now. plus free is a hell of a good price) 21 speed grip shift.

my question is this. im currently at 320 lbs. i know from previous experience that the pedals and arms and bearings that house all these components together tend to not last me very long. where can i buy quality gear that will be able to take my weight as well as some abuse. (as in when im climbing hills standing etc etc.)

thanks for the help.
