/ Geeky cycling advice
I have a fixed/single speed bike (pearson touche) which I commute around London on. I currently have a 18T freewheel cog. I am tired of the brompton lot passing me on the flats - should I go down to a 16T? Will that be two low for the slight hills?
What do you have on the front?
Stick with the 18T (I assume it's 48 on front ie 72").
16T (81") is a bit heavy for commuting and you'd spent too much time sub 90 rpm than is good for you.
Eventually you will pedal at 110rpm...
i guess your running it as a single rather than fixed (i had one of the original 2 touche frame sets and felt it was better as a fixed). if you do change i would go 17t rather than 16
Surely you don't run the chain tensioner when you have it fixed?
You don't need it at all if you have horizontal dropouts.
I'd assume it's this type of thing we're talking about rather than the jockey wheel type thing...
Like JLS says it sounds like a chain tug rather than a tensioner.
Chain tensioners are used to take up the slack chain in a singlespeed system. They look a bit like a rear mech. They don't work well with fixed wheel.
If your hub is threaded on both sides you can play about with ratios without committing to one.
Track ends are the same thing as horizontal dropouts.
Welcome to the geeky world of fixed wheel riding ;)
Not quite the same: track fork ends open to the rear, horizontal droputs open to the front.
if you set up your chain right you should be able have quite a flexible sprocket setup i can switch easily between a 15t an 18t (could probably fit at 14t without chain issues)

I am on a single speed with 48 - 18 and live in Crystal Palace. i get up the hills but its sometimes not pretty especially if tired. Problem is i am a big guy (92kg) which does me no favours for climbing. I would say over 8% i start to get into real trouble.
I do however have a speed of about 30kph (at the cadence of 90) along the flat which means i can overtake 'most' commuters and at higher cadence i can keep up with most roady's. IE heading along brixton rd into town the only people who can beat me are the ones running the lights or pushing big gears on road bikes.
As others have mentioned, try a few different set ups, go down 1 tooth at a time and you get a better feel for how things change.
