Probably asked before (for fixed):
If I change my 48/16 setup to a 48/19 setup will I need a new chain?
Tired of lame track setup cause I have hills, and I'd like to ride up them.
Anyone feel a difference when they switch out their cog for a lower gear?
And it is true that unless you race track, you really don't NEED an even numbered cog? (14, 16, 18)
Thanks for understanding my n00bey-ness.
