More than likely something is wrong with your setup. Can you post a closeup pic of your rear dropout area? Are you using a nut with a built-in floating washer, preferably serrated? Steel or aluminum frame?

Many many years ago when I had mt first FG I had a set of "Eagle?" hubs that came with the alen wrench bolts, not to sure of the name though as it was a loooooong time ago.

Hey actually there is a place to buy allen skewers. I am in the process of building my first fixie right now and I found the skewers while searching for rims. If you go to Halorims.com and look under road products, they sell colored hex skewers.

You can get allen skewers anywhere, but they'll probably just break and leave you stranded if you use them for your rear wheel. Mine did, and it was chromoly steel. Just go quick-release if you don't want to carry a damn wrench. That's what they're for.

Just go quick-release and DON'T RIDE FIXED if you don't want to carry a damn wrench. FTFY.

you are aware that it is perfectly doable to use a quick release on a fixed gear bicycle? With no ill consequences in fact. I have to run, but I'll let others finish dispelling this myth.

Hahhaaaaaa...well met.

Well... if you want to use one of those really bad on your fixie you can always use one one only on the front with a road hub/wheel; but not the rear, so you're still stuck carrying that 15mm wrench......

But there's always the nice felt beer nuts tool that can go easily on water bottle cage bosses....
You can also always hide a 15mm wrench under your saddle if there's room.....

Just get one of these....

I get a fair amount of use out of mine.

$20 for that?

Won't have to carry tire levers....

Nothing's worse that having to lug around a tire lever AND a wrench!

tire levers never presented an issue

This is coming from the same guy(me) who lugs his tools in his camelback.

I usually have more tools than are even necessary in my bag (not on purpose...they just all seem to end up there!), so someone complaining about having to carry a little wrench seems kinda funny.

i got that 3wrencho thing for like 12 bucks, thought it was worth that...

these?

Interesting. I stand corrected. Not going to do it myself, but Sheldon's usually right about this stuff.

I've done it for 35 years and not had any problems yet. However, note Sheldon's admonition to use an old-fashioned closed cam QR lever and also a steel nut on the skewer. Modern open cam QR levers with aluminum nuts are intended for use with vertical dropouts only, since they do not provide sufficient clamping force to prevent the rear hub axle from slipping under power in a horizontal track dropout.

Not to pick on TT any more, but I have an allen nut on me right now. Seems I stripped my seatpost binder bolt. So I have the allen bolt and allen nut, and need to make a trip to my LBS.

Is it a Campy seat binder bolt and nut set? If so, only the bolt part has a hex socket and the nut part is round. Also, the nut part has a ridge to fit into the frame seat binder ear, so that it won't turn when you tighten the bolt part with an allen wrench. You are supposed to tighten the bolt, not the nut. Anyway, you've already made your point, so I presume you're just doing this in a vain attempt to get a rise out of me.

Is it working?

I just think that your blanket statement about allen nuts needed clarification.

"No such thing as an allen nut. A "nut" is an internally threaded fastener that mates with an externally threaded item such as a solid axle. A "nut" has the wrench flats on the outside. An "allen" fastener is externally threaded with internal wrench flats and is technically a "bolt". You cannot connect two externally threaded fasteners (bolts)."

I think you should run for public office.

i'd have to actually say that this 'allen nut' that you keep talking about would actually be classified as a chicago bolt. just sayin'.
