Gear ratio? One at front, one at rear, connected by chain plus crank/pedals, use real fast. As seen today by lots of over-excitable types down at Vodaphone Arena.😄

1 "gear"

2 sprockets or cogs (1 front chainring, 1 rear cog)

Infinate speeds (just pedal slower or faster)

There is no freewheel ratchet mechanism like 'normal' bikes,
so riders cannot 'coast' on them. e.g. If the bike moves - so do the pedals. Because of this, riders can slow down by slowing their pedaling speed or applying slight back-pressure to the pedals.

How good is track racing?!?! Yeah! 😄

Well, track racing and fixies have been around a lot longer than multi-geared bikes. I still see old timers riding (slowly) around town on them. John Nicholson (previous World Champ?) was walking around Vodaphone yesterday..

Better to sustain injury doing something you enjoy than live wrapped in cotton wool, not doing anything for fear of getting hurt..

You could never ride a bike in your life and fall down the stairs one day, destroying your knees..

It's a matter of changing your gearing to suit your knees
and/or the race you're in! You are able to change either the
front chainring or the cog (or both) to get a smaller or
bigger gear.

pfft. that's lightweight 😄

and there is no head wind and no gradient. Shame shame.

Yeah.. <hangs head>... but to come clean, I'm running that gear because that was what was on the bike when I bought it and I've not had any desire to change it. I've only got a limited selection of track gears and figured I should learn on the
smallest gear I owned.
Since the season ended before I really got into racing (got in
a decent crash though - still carry the marks...) I never started playing with gear selection.

lame-o-excuso-hippy ;-)

what???!! That's only an 82.7" (as opposed to my 90 dead 🙂
That's a warmup gear :P Time for a new cog my son! The
biggest I've ridden is a 50x14 (96.4) in a motorpaced
event, it felt really good till the derny pulled off the
track! Gemma

Awight grrl you're on! ;-)

<grunts><scowls><pretends to be Ryan Bayley/Sean Eadie>

Along with the piles of other track gear I'm in need of.. a MASSIVE gear is added to the list :P

If we meet in a race, I'll fit it and hopefully my lardbutt will create enough momentum rolling down the bank to wind it up before
you destroy me with an early jump! 🙂

DRS can film/photograph my knees exploding ;-)

- Who's got a spare 62T chainring lying around? 11T track cog?

Hip,

All this talk about inches made me think to ask you what
sort of gear you have planned for the fixie? On mine I run a
76 (42x15) coupled to a
172.5mm crank arms which I find good for most stuff I do
around Melbourne metro area which includes, the
occasional North Road Ride, South Morang to Mordialloc
and occasional rides to work. I tend not to ride this
bike in the wet as it does not have sealed bearings
(Sealed bearing Suzue hubs with lockring, sealed BB and
Headset are coming soon). On the flat it's not
unreasonable to sit on 40km/h (cadence = 105rpm) and for
the downhills comfortably allows for around 50km/h
(130rpm). This gear also works when the road goes
slightly upward and the longer cranks also help in this
department.

Some thing to be aware of when looking for cranks is your
bottom bracket height. If the cranks you chose are too long
you will have a much reduced pedal clearance when taking
corners. You may need to look at something in the 165-170
range if this is likely to be a problem.

Another piece of advice is to use a quality chainring. The
rounder the chainring the less likely you are to throw a
chain. If the chainring is not perfectly round then you will
see the tension of the chain drop or increase significantly
as the cranks are turned. I'll leave it to your imagination
the potential carnage due throwing chain off the ring and it
then becoming stuck between the spider and the crankarm.
This is probably more critical when using a 3/32nd road
chain setup as opposed to 1/8th track chain setup as the
former is laterally more flexible.

And when you finally get this beast of yours on the road
head down to beach road and jump into a pack. Besides the
strange looks you'll get due to the fact your bike is not
like the other bikes you will also notice that on the
uphills you climb faster than the geared bikes despite your
bike weight being nearly twice the weight of the other
bikes around it. And better still you get to pedal for the
whole ride.

Cheers Geoff

btw. I have had a quick a look at your pics from the 2004
Madison Meet at
VA. I notice you got a few shots of me. Once I've had a
better look I might get some copies from you if
that's ok.

Nice website Gemma. Very er.. minimalist. (in a zen
type of way.)

This is my website. Needs some prettying up.

yeah yeah 😉 When I have a sec I will fix it, I promise!
(The jpg that is, my bum has taken years of cultivation and
isn't going away anytime soon 🙂 Only knocked up that
'minimalist' page last night, haven't written html in many
moons, most of it isn't working yet, too many typos. Gemm

I was going to see what's available and pick something in
the lower/middle range. 63xc guys suggest high 60's or low
70's but that's probably for offroad fixie riding and might be
too low?

The SS is 32:15 with 175mm cranks and 26" wheels w/ slicks.
I find myself spinning out quite and bit and it really needs to be
geared higher, but I like it on those days when I'm really tired (often).

I got a new fastest cadence the other day on it: 34 x 6..
um.. racks notoriously slow brain.. 204bpm 🙂 Cracked 200!
I want a cadence computer though, for an official reading. I
find it really hard to actually count as fast as I can pedal!

I wanted to fit 165mm to match my track setup.

Damn my imagination! Sounds painful.. 🙂
I will have to start trying to skid the bike as soon as it's built
for handling these emergency situations.. mmm skids..

I -have- heard that fixies climb faster than gearies.. I like the sound of that! If I have juice in my legs I often beat (slower) roadies up hills on my commute on the SS because they gear
too easy or too hard for the climbs.
