What fixed Gearing do you use ?

48*17=74.2

 

[Landslide]

68.3"
When living in Sheffield, pretty much every route involves a hill at some point.

on the road? I say bullshirt.

48*17. Hills(?) are all short and steep round here, so you can just grind up them.

I think I used to ride what was called 'evens'.
20mph at 100rpm. I can't remember what the ratio was (and i'm too lazy to work it out). I've got a feeling that it was lower than all the ones posted up here.

It was still murder on the hills (up and down), which is why I sold it.

20mph at 100rpm would be a 67.2" gear (so 46x18 on 700c x 23mm tyres).

I use 46x17 on 700c x 25mm which is 71.4". I use this same gear for flat commuting in London, going round Richmond Park, inducing leg pain in the Surrey Hills and lots of Audaxes including The Dean 300 and Severn Across 400.

For an upcoming flat 300km Audax (London to Thorne) I might gear up to 75" (or even 79") as it gets mighty flat after Gamlingay.

I am indeed a messenger. I run 48 x 18 on the road.

 

[Origamist]

53 x 12

I ran 53/13 on my 20" fixed folder....

On my 700c bikes I run any of the following combos:

42/14
42/15
42/16
42/17

I use the bigger gears for commuting, less out in the sticks.

I have this picture of you opening up the shed and having a row of identical bikes all except the back sprocket. " Hmm I fancy the 42/16 today"

4 fixed bikes would be very nice indeed...but I only have two! Both have double fixed rear hubs - hence the four ratios!

I'm new to the fixed lark and I'm using 46/17 (about 71-72 inches) around Edinburgh. I'm not having any problems getting up the hills round town and it feels a bit low on the flat so I might stick a 16 on the back and see how I get on with that.

 

[Will1985]

Mine changes depending on where I am. 48x18 to fit the medium gear criteria when I do 10TT test runs, 48x17 anywhere with some mild hills, 48x15 or 14 in Norfolk when feeling strong!

I use the Miche carrier system to make things easy.

 

[dudi]

is the miche thing the cartridge that screws on that you can slot the different sprockets on? then lock-ring in place? how is that? does it feel secure? I've fancied that, but at the moment I just run a standard sprocket. mind you, i reckon if i just bung a 15t on the other side that'd be enough variation.

 

[Greenbank]

I've used the Miche carrier for 8000km without a problem. Hasn't ever come loose.

I have 46x17 on the bike, but carry an 18T sprocket in case I get tired on an Audax and need a bailout gear.

 

[GrahamG]

I've just changed from a 64 1/2" to a 68" and will no doubt feel the pain. However, after meeting a few other Brizzle fixed riders I think that my lower gearing goes to show not that I am less manly, just more of a fat bastard

Power:weight - that's what it's all about.

 

[Fixedwheelnut]

Different gears on different bikes;
49 x 18 = 71.6" medium gear on my Lambert


46 x 18 = 67.3" on my Ron Cooper Audax bike


and currently a whopping 47 x 14 = 88" on my Graham Weigh for some TTs and commute/training
