Feel free to use this thread to post your "is this fork bent?" inquiries

i will start with this ironman i saw on CL..

yes

yup

It's not bent!, it's just fork leg refraction you see there!......

Chombi

thought so.. i didn't notice it at first but today i was looking at the ad again and was like... hey wait a minute

same bike? (if so, price has gone up while the parts have come off :lol: )

Still bent...looks like the frame too.

Forget the fork......that is an ugly bike (the fixie).

Trick of the lens.

I say it was cold-set to make a more maneuverable bike.

as a fixie it is pretty janky.. he should have left it as a roadie imo. double chainring with biopace doesn't excite the fixie crowd too much.. and those bars need tape.

This one always bothered me

Apparently the ills of bent fork are remedied simply by turning your drop bars back 180 degrees. I see lots of bikes being ridden that way.

Huh?

That's right. Stop whining about your bent forks. Turn up your drops and ride, you big babies!

Are those chainrings biopace? How do you make a fixie with rings which don't have a constant radius? Inquiring minds want to know...

It works for the same reason it works with a derailleur. http://www.sheldonbrown.com/biopace.html

I've discovered a great feature, apparently the folks here in the "hood" have known for some time. If you flip the bars a certain way, the brakes become "power brakes" turning the weight of your upper body into a "increasing pressure tool".

That's right, David. There are all sorts of benefits.

I thought the flipped drop bars were the international symbol for " busted for DWI"?

Oh, I get the variable leverage idea. But...but...but...with a derailleur you have something to take up the chain slack, with a fixie you don't. So when the long axis is horizontal the chain will sag. On the other hand, maybe that's a style thing, kinda' like droopy pants.

the change in tension with biopace rings isn't enough to make a difference on a fixed gear

I was kinda wondering the same thing, so I guess we're not alone in our confusion.

But it doesn't. The same amount of chain is wrapped around the chain ring at all times, so chain tension fluctuates only a tiny bit as the crank rotates. But Sheldon had better luck with this arrangement than I did.
