Got the bike named above, upgraded(?) with mavic Crosslands to tubeless, mallet 1 platforms when I got the bike, but otherwise right off the floor. Did some searches for what upgrades to do first (most significant improvements) and it seems a little jumbled. So im asking, what upgrades should I do first with this bike (going to disc brakes seems to be step 1)?
