Just use a Miche adaptor with cogs, makes changing quite easy (you can leave the 48 on for track usage, 48x15 gives you the same ratio as 51x16). Also 48x19 is spinny as hell..
I also would shorten the brake inner cable a bit
I'm good how it is really, I have reason for 51x16 one that I'd rather not say here.
48x19 is perfectly fine.
Only if you're used to grinding, 48/19 is fine, around 67Gi.
This.
Looks good - you may as well get a road bike though.
Save this for track.
I don't enjoy riding roadbikes as much and I feel I'd need to spend more to get a good one.
