what is this little rubber thing? i see alot of fixed gear bikes with them attached in different areas of the bike. I have seen most either on the top tube or seat post, In this picture it is purple and on the fork. Whats is for?

where's the pictures?
but i'm guessing a knog

I'm guessing grease zerk

it's a dinglehopper, or maybe a doo-hickey

It's a troll.

Sorry idk how to post picyures properly, try opening the picture in a new tab.

yep, i totally know what this is.

i saw the code for it when i hit reply and then pasted it in a browser. still don't know what it is though. definitely not a thingamabob, for sure.

it's a knog frog. it's a ****ty little 1-LED light that hipsters use to be able to say "i'm safe, i have a light" while still not actually being able to see anything.

knog frog aka. hipster cyst (bsnyc)

You're right! i looked up a knog and thats it. I kept trying to search for a mini tube patch kit or something. That is what i thought it was. A mini patch kit in a casing like that would be cool.

you could VERY easily modify one to carry a glueless patch, as long as the patch is the size of a 2032 battery.

however, knog is a really cool company with awesome designs and the knog BOOMER is DEFINITELY going to be my next non-component/metal attachment bike purchase.

i need a streamliner road DLX for my road bike first.

omg! Those are so totally cute! They think they're people!

I put one on my rear hub, not sure how it looks in action.

Did you do this as you were building the wheel up? I can't imagine myself reaching through the spokes to get that thing on there. I can't even reach in to clean my hub.

I've seen lots of people do that and it you dont really see it

it's super easy to put it on a hub, unless you are running 84 spoke wheels or something.

if i'm to put any rotating lights it will definitely be this

Uhhhh I believe its to BE seen... and not, in any way, to SEE... sooo uhhh... yeah... actually a fairly nice product at a reasonable price.

u are right. But the single LED doesn't really do the "being seen" factor too well either
