I have a Surly cross check which has currently got gears. I am starting to miss my fixed gear that i sold to buy my Surly.

The main problem for me is that is is quite hilly where i live (Yorkshire, UK) so my question is:

What options do i have to make a fixed gear usable in a hilly area?

Have seen the Sturmey S2C hubs but they are SS not fixed, but give me the option of running at least 2 speed.

Also seen the Surly Dingle Cog - does this need a double front chain set or does it run off the single front?

Any thoughts?
