Best Gear Ratio 48:16 or 44:16 or.....

Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

Some of you guys must only weigh only 90 pounds to be able to push 80+ gear inches on hills...

You can calculate for gear inches, gain ratios, or speed at various rpms.

46/16 = 75.8 gear inches

48/18 = 70.3 gear inches

I set the wheels at 700c x 25, 170mm cranks.

190 lbs and use a 53 x 16 on a single speed set-up with two brakes. I'm riding all flats with only an occasional stop (maybe every 1.5 - 2.0 miles sometimes as long as five miles! ). Works great; slow to start, but once it gets rolling its all about eating up asphalt. If I had hills I'd definately have to drop the gearing down a bit.

I live in the Silverlake area of LA which is somewhat hilly, so taking that in account, my ideal strength-to-weight gear ratio is about 70 gear inches which is about perfect.

I run about 68-69 GI, its great cause I can slow down and speed up really quickly, which is pretty necessary on a crowded bike path. Unfortunately I do spin a lot if I go on a longer ride, but its worth the compromise.

So out of the 17t 3/32 cogs available on Bens Cycle, which brand is recommended?
How does the Euro-Asia Deluxe, Formula, Milwaukee, White Industries, stack up against each other?
Thanks.

I have EAI and they have never given me any problems over many, many miles. I have no experience with the other cogs.

I was living on Nantucket when I got my fixie, and got it with a 48x14. Was great on a flat island.

Moved back mainland, not so good, so I am going to change to a 17 in the back, brings me down to around 70 i believe.

<Noob question alert/>

going from a 14 to a 17 in the rear will i need more chain?

Y'all keep talking about skid patches. What do you mean and how do you figure out how many?

I have a 46/17 on one bike and a 48/18 on the other.
It equals out about the same.

I love it.
I started out mashing and didn't really know it.
Now I've developed a cadence and can go just as fast as I did with 48/16, I just spin more now.

70 gear inches or so is great.

I think the messenger's are going for around $90 with the chainring included. Maybe someone can tell you if there is a good replacement chainring for the truvativ's or another crankset that will fit the powerspline BB on your Pista.
i did some searching and i came up with the BCD for the stock Truativ Tuoro Track 1.1 48T on my Pista being 130. and after checking out the charts i came up with 47/18 being what i would like to try running. i am going to get a few other cogs while i am at it and try a few different set ups. i like the 18 skid patches and the 70.5 gear inches that the 47/18 will give me. i guess my next question is did i find the right size BCD for my cranks being 130? if not, i am not apposed to getting a new crank set and BB, but if i can save some money i would like that too(i want to buy a new mountain bike this spring. my friend wants to ride some trails and wants to buy my old one). thanks again, this thread has been great for me. and i really didn't mean to try and thread jack OP, you started a realy good thread and it has been super helpful!

You'll most likely need to add an additional link to your chain.

You can still get skid patches even if you don't do it deliberately, especially riding on loose surfaces. It just takes longer.

True.
But I know a few 150 - 200 pound riders who are very strong climbers but definitely have trouble pushing 80 GI up moderate to steep climbs.

i have to do just that, push my 81 gear inches up hill. i live at the tops of about 6 blocks of steep up hill. if i go up the right hills i can manage to get up 3-4 blocks worth of them, then i have to get off and walk and push my bike. it is killer. i feel like i am going to die. that's why i need to get a new set up. now i need to find a red (i am in the process of making my bick blue and red) chainring that will fit a stock pista Truativ Tuoro Track crank.
