What's your favourite gear ratio?

Currently 48/16 - 78.9 Gear Inches.
Need a 17t or 19t cog, 48/16 only 1 skid patch and way too high for brakeless.

Bit late to the big/big small/small debate, but something that's not been mentioned is small will mean a bigger jump if you have a flip flop hub and flip the wheel over by the same number of teeth.

For example my polo bike's road gear is 32x12 which is around the same gi as 42x16 and 44x17 (actually a bit higher than both), but compare the difference in gi's if you add four teeth (which I can easily fit on my dropouts without changing chain length):
32x12/16 = 17.9gi difference
42x16/20 = 14.0gi difference
44x17/21 = 13.2gi difference

PS: I ride fixed with not one but two brakes. There is nothing wrong with doing this.

As soon as I have a disc guard for my polo bike I'll be fixed with 3 brakes when riding on the road. :)

measures out as a 130

so .. 44t 5-pin 130 1/8th ally ring pls, and the spanner too

recommends for suppliers to the fix-ed market pls ..

aha 2-fer-1, excellent

ty sir

and its TA, a well-familiar name to me

• lathe-turned [good]
  

heh TA rings on Stronglight cranks used to be the go ..

the 50t on it now is an Alize, also TA, good nick too

46/16 - Vancouver is pretty hilly and its nice to have an easy ratio for going up... just sucks for going down.

This makes you the opposite of the single-speed-with-no-rear-brake twits. Congratulations, you are the antitwit.

Wait what?

Boom boom...

hm, Parker's prices seem ok after lookin at what they charge in the US for TA http://www.sheldonbrown.com/harris/chainrings/130.html#44

3:1 at 48t,16 and 79.1", goes lovely once at speed, but knees want to explode up hills and could be faster when on a mission or downhill :(

so .. 44t 5-pin 130 1/8" TA ordered from Parker, but so far they seem not-in-stock

an dammit just spotted my freewheel+fixed-cogs are both 3/32" :: a fairly no-name freewheel at that, no maker id spotted yet

id really prefer 1/8" .. but this gives me a chance to decide if 44/16 is viable, go up or down if not eh

ok this guy in NL seems to have some useful NOS kit

ordered a Gebhardt chainguard 130bcd. http://www.defietsenmaker.nl/index.php?item=gebhardt-chainguard-130bcd_&action=article&group_id=10000040&aid=1572&lang=EN

Hi all. I'm currently on 42-16 Single speed. Would I notice much difference if I went on to 44-16?

About 30cm of development... Not a massive difference considering both ratios are pretty light. One of the beauties of riding fixed gear or single speed is that you're always in the wrong gear; as soon as you find the perfect ratio you're geared too low ;)

Thanks v much.

Now that's a ratio...

49/19 is mad fun for me @ 70-75kg, have it on my beater, keeps me off my nicer bike more than it should.
probably my favourite ratio.

Currently running 45x17 on the brooklyn and it's real nice, perfect for the current build.

meh, no new drivetrain for me this weekend, he sent a 135

hes sorting it ok but

i guess the Regina 16t wont mind soaking in Starrett oil a bit longer

anyone want a campag-record-fitting chainguard

47x18

Uphill, heavy wind I can easily tell you which ISN'T my favourite gear ratio. 48x16

certain number x a different number is the perfectious.
