People who barrel down the hill during a charity ride on their $4K Cervello only to die on the following climb because they spent a ton of money on the bike...but don't ride it except during charity rides.

People who post on BF, don't list a location on their profiles, then say stuff like "Great ride here yesterday!" and you have no freakin' idea where "here" is...

People who type C02 instead of CO2. It's carbon dioxide, people. Not carbon dizero.

Hearing a click, tick or creak on a group ride and not being able to figure out if it's my bike or someone else's.

The word "weights" used in place of "weighs" as in "this bike only weights 18 pounds."

I've seen this way too many times to count on the forum in the last few weeks and just saw it on a CL ad.

Maybe I should be an English teacher instead of a music teacher...

"I could care less" instead of "I couldn't care less"

"I could care less" means you do care at least somewhat.

Salmons in the bike lane.

My bike weights 19 pounds
Has Duroace breaks
And Duroace peddles
But I got a flat and had to change my wheel.

Yes, I feel your (or maybe you're) pain.

when b****es don't wave when others wave at them.

good roads being maintained like ditches.

People who say "I seen" and the word "basically"

The NSA.

Bike mfg that put words all over the frame. Put the company on the down tube and maybe the seat tube, model on the top tube. That's it.
As an example, Bianchi makes the Oltre frame and puts crap like "UTSS ultra thin seat stays" and "KVID kevlar vibration damp whatever the hell" on it.
I don't want that crap all over my bike!

Front Tinted windows that prevent me from seeing a driver

gotta plus one this. one big ass logo on the downtube is more than enough.

I believe the logos on the bikes replicate race bikes...where the logos are overdone to make sure they get on camera from whatever angle the guy on the motorcycle is shooting. But still a fair pet peeve. I'm sure other's would be upset if their replica race bike didn't have the same logos as the pros.

I don't like logos on my bike either, and specifically asked the manufacturer of my Ti bike to NOT apply one. All it has is a badge on the head tube and (unfortunately) a name on the fork which I may still paint over. In addition to looking more old school / classic (which I like), I figure it might make it less attractive to thieves as it's harder to determine value (and sell). If someone wants to find out the make/model they can ask me.

PENNDOT. seems like they spend more time ****ing roads up than fixing them.

"Hey we just repaved this back section of road for you! Now we're gonna chip seal it for no logical reason!"

bike thieves

+1, never understood why they do this.

Chipseal.

Lawyer tabs on my fork dropouts.

Agreed. Terrible.

Joggers/walkers who jog/walk two or three abreast on the bike-path.

With ear buds....
