Why does my track disc have a hollow axle?

I have an old Zipp1150 purple disc wheel. Yes it was made purple, not repainted. And its threaded for a lockring, and spaced for track...but for soem reason its got a hollow axle. I have already broken a couple skewers overtightening because the first time I used it, I threw the chain because the wheel slipping forward. So I am still on the hunt for a quality skewer to put in it. I already know about pitlock, but are there any other skewers that are steel and alan key?

I have seen a few in online stores, but they all seem pretty ****ty so I am wondering if anyobdy here has found a decent one.

Also, why the hell does my track disc even have a hollow axle? I bought tensioners to use in conjuntcion with the next skewer I find, but I don't know how tight you need to go if you're using tensioners, because my understanding is that they are just supposed to help out with keeping the wheel in place...not take the whole load.

I contacted Zipp and its possible to put a new hub in, made for a solid axle. but that costs 300 bucks and seeing as this is my secondary have because I love the frame bike...I don't really want to spend 300 on the rear wheel.

I'll post pics when I get home.

A track disc with a hollow axle is quite normal. Look at Dura Ace track hubs, they have hollow axles too. It saves weight. However, you would seem to have a road axle in your track hub if you can fit a skewer through it. OR are the ends threaded and intended for allen bolts?

If you've got a road axle it would be designed for a 126 or 130mm road hub not a 120mm track hub. The extra 4mm would play havoc with a quick release. Spacers might work if this is the problem.

But check for threads, I'm putting money on it being a hollow track axle designed for 2 allen bolts.

Is this your bike per chance?
http://velospace.org/node/2784

If that's not you, send the owner a PM on velospace.

looks like it's been respaced, leaving not enough room to get a proper track nut on the hollow axle. What's the current spacing? I could be way way off. In fact, I don't even know what a 'bicycle' is.

That photo also shows the bike with a 650 front wheel, so I'm guessing the previous owner liked doing barspins. Oh, and the rear disc just looks awesome with that frame.

Well to remind you Spooky, the velospace picture is the bike when it was owned by another person, I just bought the frame and wheels from him. But one reason, is that its a 650c front, and a sloping tt so the front is pretty low and has pursuit geometry. In order to be comfy on the street, you would need risers I suppose.

I just took out the axle, and tried threading track nuts on it and they fit. It just seems like somebody cut the axle too short to fit thread them on. Which would make it a whole lot easier for me to just buy a new solid axle...oh how I have dreaed using a skewer with it.

Yeah, I originally just bough the frame, but the guy who was very nice decided that the disc needed to stay with the frame and we did a swap of some parts to make that possible.

It has a 650c front wheel because thats what it is made for. you can't put a 700c on it.

Oh, i have always loved that bike... I have seen it a few times posted here and there..
lucky you, and as for risers on a pursuit... I think it makes since and looks freaking hot.

i am putting together a colnago pursuit and had been looking to that bike for inspiration...
simply sick, I want a flat disc wheel so bad.

Yeah, i really loved the fraome too, and when I heard about the owner selling it, i had to jump on it.
It is a really unique old tommasini, and they have neat paintjobs. I am not sure when have max matched wheel sizes on teh track was banned, but it must have been made beofre that.

Hockeyteeth...not sure if you are being sarcastic but yeah this frameset is designed for a 650c front. no barspins here.

Someone has been selling Moscow time trial bars on eBay lately. I considered buying some for ****s and giggles, but the prices kept going far beyond me meager means.

No way you can pull off a barspin with that geometry.

and since the fork is made for a 650c wheel, it wont even spin all the way around.

I don't think it would even be possible to ride in the drops with geometry like this... you would chip a tooth.

MMMmmmm Colnago pursuit. I just love the old curvy tubed pursuit bikes. Even if they aren't the most aerodynamic or even legal anymore...they are just beautiful.

Sell the Pista, not the Bauer. That Bauer is too wiggity-weird and awesome to part with. Plus since it already has Deep Vs and risers, you could probably sell the Pista for something like $900 and save some kid some work.
