Genuinely I don't see why?

Larger gear = I can mash up hills faster. Again, it's what works for me personally. If I had a smaller gear, climbing would take me longer. The big gear works coz I am relatively good at mashing hard, just not sustaining it for a long time. If you were wondering why I have so many ratios, it's because all my rear wheels I run fixed/fixed.

EDIT: Oh and my polo bike has a 46:19 although I'll probably change that to a 22t cog. And maybe a smaller chainring also.
