Yeah, that's what I'm running now, and it's pretty much perfect.I dig my 25-11 setup.
I've had close to 2:1 for a while - 32/15 and then 25/12. There is a formula that takes wheel size into account, and you come up with a number that is supposed to be close to 55. Anyone have the formula?
You'll still have plenty of cog/chain contact with a 16.WTF? I have 32/16 now and I need to use a half link (which I don't have, of course) in order for me to use my DMR STS tensioner dealy in the 'pull up' mode. I can use it in the 'pull down' mode but then I run a risk of my chain coming off the rear gear.
I guess it's ok... if the chain stays on. I'll drink a quick beer and go for a test ride right now.
did you push the chain up or down with the STS?I used to run the STS on my STP too. With a 15. Make sure you're actually running a single-speed gear and not just a gear out of your cog. I made that mistake. Chain came off pedaling into the green lake jumps... the soccer game stopped to see if I was ok.
I think sixgun meant "cassette" when he said cog.did you push the chain up or down with the STS?
also, what difference is there with the cogs vs. single speed gears? aren't teeth teeth?
Pushed down with the STS. What I did was take apart a couple old 9 speed 'cogs' and used the spacers out of them. And then I just grabbed one of the old gears and stuck it in the middle. The gears in a 9 speed are designed so that your chain will easily move to the next gear when you shift. This also means that your chain will fall right off if there is no gear there for it to shift to.did you push the chain up or down with the STS?
