Always Be Cycling

Put. That. Coffee. Down.
Coffee’s for cyclists.

You think I’m messing with you? I am not messing with you.
I’m here from downtown. I’m a messenger from the streets
And I’m here on a mission of mercy.

You’re not cycling enough. You’re not pushing enough.
You’re not living enough.
Because only one thing counts in this life:
A–B–C

You hear me?
A–B–C
A — Always
B — Be
C — Cycling

Always. Be. Cycling.
Always be cycling  on a fixed gear.

“Hey, I’ve got a road bike.”
Always. Be. Cycling.

“I prefer multiple speeds.”
Always. Be. Cycling.

“You can’t coast!”
That’s right. You can’t coast. Life doesn’t coast. Gravity doesn’t coast. Your legs don’t coast.

You know what it takes to cycle a fixed gear?
Brass ball-bearings.
Steel calves.
The will to pedal downhill at 40 miles an hour knowing if you stop, you fly over the bars like a lawn dart.
That’s what it takes.

You call yourself a rider, you son of a derailleur?
I’ve been in this game fifteen years.

What’s your gear ratio?
What’s your skid patch count?
You even know what a skid patch is?

You think this is a hobby? This is the Tour de Life. And winners ride fixed.

First prize is a titanium frame.
Second prize is a set of foot straps.
Third prize is you’re back on training wheels.

You want to save your quads? Go ride a recumbent.
You want to win?
Cycle a fixed gear.
You don’t like it?
Go pedal somewhere else.

But if you’re staying here, you will always be cycling a fixed gear.
Now get out there and ride your bike like it's a shark and if those pedals stop turning you die.
Always. Be. Cycling.

Great Value

Been riding for 2 years now, primarily as a bomb proof city commuter to work and the beer garden. Note that bottom bracket will fail in super cold Chicago weather.
