(Disclaimer, I have not posted on these forums in entirely too long. Sorry, folks)

I've been primarily a road cyclist for a long time now, and recently picked up a Pure Fix India as my "around town" and commuting bike. I love it and it's a ton of fun, but I'm noticing that I'm putting way too much effort into the pedals for not a whole lot of return.

Initially, I thought "saddle height" and/or tire pressure, but neither of these seemed to remedy the problem.

So, I'm wondering if this is an issue of:

A. Getting used to the gear ratio/bad cadence management
B. Not having used platform pedals since who knows when
C. Something having to do with riding on Thickslicks after being used to the 4000s on my road bike
D. Something else

Pedal straps have seemed like the obvious choice, but I wanted to check with other single speed/flip flop riders and see if maybe it's something simpler than that.

Thoughts?
