I am running a 44/16 set up on my singlespeed commuter which I find is pretty good but a bit spinny in places (10 mile each way London commute).
I put a 14t cog on the back today and although good fast fun in places my knees are going to burst if I keep it on and God forbid a windy day!
The jump is too big. Will a 15t be a good compromise or is that still a bit of a big gear to push? Wiggle say they are all discontinued (£3) and On One sell them for £16 so a bit of a pricey mistake if it is!
Any links to a cheaper 15t cog?

44/16 was a bit spinny? 😯 Is your commute totally flat?
44/16 was killing my knees so I converted to 32/16 at the weekend.
it is reasonably flat but quite a few draggy inclines. I have legs of steel ;)....not 44/14 steel though!
Commuter is on 700/23 wheel and tyre combo if that makes any difference.
gear choice is quite a personal thing, and will always be a compromise.
15T 10.99 http://www.chainreactioncycles.com/Models.aspx?ModelID=17775
probably cheaper version on ebay too.
why not try 46/16 or 42/14, both will give you an 'inbetweeny' gear like you seem to be after.
or is it a case of rear cogs cheaper than chainrings?
FWIW I'm running 48:16 and it's perfect for my commute, but it totally depends on your legs, your commute, your pedalling style etc.
Assuming a 26" wheel, the following table will let you play around with gear inches, you are adding 14% by going from a 16 to a 14 so its quite a jump.

So as recommended, looking at changing the chainring will give you a closer step increase.

just spin faster?
i run 48/17 on my singlespeed roadie bike although i do find it difficult when it gets lumpy

If he's having trouble even [b]turning[/b] that gear, how is he going to be able to spin it?!
I'd change the chainring TBH, go for a 46/16.
My Langster (again 700c wheel) came with a 48/16 set up and that was pretty much spot on but I eventually changed to a 17T freewheel as it gives me just that fraction more leeway on hills/headwinds now.
In calculating ratios by the way, one tooth on a freewheel is roughly equivalent to 2.3T on a chainring.
Assuming DX will fit just spend the £2.70 and try it - JFDI
Thanks for the replies and links.
I have ordered a 15t onza ring with bling spacers from Wooley hat shop so hopefully that will be a good compromise.
The Shimano DX sprocket has a £3.99 delivery charge for a £2.70 item!
I don't want to change the front chainring as they cost a bomb on an XTR crank.
Thanks

Ahh... didn't check that

It's a London commute. 😉
44/16 is certainly a bit spinny as far as I'm concerned on a mountain bike. It'd be just about right on a 700c wheeled bike, maybe a little bit quick if it's flat.
44/16 = 72 gear inches
44/14 = 82 gear inches
44/15 = 77 gear inches
46/16 = 75 gear inches
Samuri, it is a 700cc wheeled bike (Roadrat).
Thanks Chunky Paul. Not that that means much to me in way of pedalling feel but I can see it should be a good middle ground.

he said he's finding it a bit spinny in places?
