What fixed Gearing do you use ?

[dudi]

just gone up to 48/15, which is 84.1 Inches.
Find it much better, hardly needing to use the brakes at all.

Did my 12m commute this morning, took an average speed of 20.5mph too! is nice, i like.

42 x 16 = 69gi. I often find I'm spinning like a maniac but I have to contend with the Archway Road on the way home and don't feel ready to increase the gi just yet. Maybe in a few months time.

 

[Amanda P]

46 x 18.

Or 69" if you prefer.

 

[jim_digriz]

Same here-69".
I'm getting fitter, so a change is in order!

Here's the low-down for choosing your fixed gear length.
Weigh your bike and include the full water bottles etc. Mine was 22 lb.
Reciprocate 22 = 0.045.
Multiply 0.045 by 1000 = 45. That’s the 'climbing' gear.

Now imagine your bike has a Sturmey 3 speed. 45 inches should be the No. 1 gear.
No. 2 gear will be 60 inches and No. 3 will be 80 inches.

The 'Fixie' length for a 22 lb bike is midway between 60 and 80, which is 70 inches.
It was a 52 x 20.

48 x 18... 72"

Not mine. Some big tall Dude in Oakland circa 2004.

 

[jimboalee]

52 x 15, 14" wheel = 48"

Some small son type Dude in Solihull.

Not mine. Some big tall Dude in Oakland circa 2004.

I should hope not - strapped pedals and no brakes?

Honestly, that was his commute bike. He pulled up and threw his leg over the handlebars, or should I say 'stepped' over the bars. He locked it up with the lock that was already on the metalwork.
He was wearing an A's Baseball jersey and baggy shorts with old style 'shoe plates' - yes, difficult to get off the pedal in a hurry. He looked in his forties, about 6' 6", with enormous quads and a couple of tattoos.

I was so impressed, but didn't have the nerve to say anything. I came back to take a photo of the bike.

Forty two sixteen

although not at the moment as SKS put the wrong fuggin' bolts in the mudguard packet so I have to go down the LBS for more parts...

I've just switched to 68" and seem to be getting on OK on short rides so far but I've not hit multiple hills yet!

 

[Greenbank]

Down to 67.4" (46x18 on 25mm tyres). Helping to teach the legs to spin more.

 

[Kirky]

Training and commuting 39x16 = 65.8" Racing 56x15 = 100.8"

Sorted.

 

[EasyTom]

I'm on 49-18 which is 72" - great on the flat but a bit hard up our Devon hills
