Need help identifying a hub - broken alloy axle.

I'm scratching my head on this one. I have an Eclipse road bike with a sheared rear axle. I'm looking for a replacement axle, but the hub has no identifying marks.

I'll try to attach photos of the alloy axle and the hub. I thought it might be A-Class, but no similar spares show up when I Google it. The Hope XC axle is very similar, but mine is threaded on each side for the spacers, while the Hope spacers just slide on.

Anyone want to wager a guess on who makes this hub, and where I can get a replacement axle?.

While the hub shell looks campy-ish the higher end hubs did not use cartridge bearings (except in the freehub body) and although their lower end hubs did, the axle end pieces that screwed on were different than that depicted in the photos.

It could be a hub made by Formula.

It also looks like it could be an axle from a Novatec hub.

I vote Formula. It's very much like one on a bike I have worked on (but don't own). The hub has been replaced now with an Ultegra one.

It would help to have more information about your bike and wheel. Is Eclipse the manufacturer's name or the model name of the bike? What year is the bike? What are the specs of the other parts of the bike? What other information can you tell us about the wheels such as the rim make/model?

It's an Eclipse brand - 6061 frame, carbon fork, 105 components. The previous owner changed the wheels (said he paid 250 for the wheels) AND removed the rim and hub labels (if there were any).

what year and which model Eclipse? One can't research specs without this info.

The wheels were replaced - they are not the original wheels.

A-Class ALX320 Replacment Rear Axle Alloy. Compatible with ALX (not AXL) 320 / 320 DX / 330.

This is the most similar axle that I found. Unfortunately, only mail order, so I cannot check fit.

So what do you want from this board? You have aftermarket wheels on your bike that you bought used and have no clue what brand they are and you seem to expect that someone on here might help you identify what you have from the picture of your broken axle and the s**ty picture of the hub shell? What, so you can feel more confident in your decision to blindly buy a replacement part that may/may not fit off the internet?

Take some measurements and give Niagra Cycles a call and see if they will measure what they have and compare for you. OR spring the $17.15 + shipping and take a chance that it might work.

Not a whole lot else us folks on the interweb can do for you unless someone just happens to come along that has the exact same hub and that they can identify it as a match for yours from looking at your pictures.

Some times you just gotta take a chance because we can't check the fit for you either...who knows, maybe it will work out for you.

Niagara gives some specs that you can compare with your axle: length, diameter, and thread pitch. Knowing the length of the Niagara item, and using the screen image, you could use a ruler or calipers to get proportions of features like thread placement and location of the raised sections. This way, you can narrow down the similarities/dissimilarities to help you decide if you should purchase. I was able to choose a replacement BB spindle on this basis.

Thank you.

I've now done that and it looks like the A-class axle fits the measurements exactly, though the shape is slightly different - the ALX320 axle has two ridges to space the bearings, while mine has a wide area. I'll go ahead and order it and give it a go.

I'm impressed with the variety of axles the hub vendors have come up with; it must make servicing a nightmare.

I thought someone would recognize it from their own dissassembly/repair efforts. It's quite distinctive.
