View Full Version : Spin Trispoke Hub Question

So I just picked up a cheap Spin Trispoke for one of my bikes, and it looks like it's missing a piece of the hub.

On the drive-side, the aluminum doesn't stick out nearly as far and there's a threaded area, as shown:

I'd assume that this is so that the wheel can be used for the front or rear, and that there's another piece required to use it as a front wheel (or rear, but that's not what I want.) Is this correct? And if so, does anyone have close-up photos of a piece that fits into there? I'm wondering how much work is involved in making this wheel complete.

Thanks!

I'm reasonably certain that Spin wheels had hubs custom-made for their setup, so you'll have to find another Spin wheel to cannibalize. This might not be tough- Spin wheels were known to turn into triangles under the influence of high-pressure tires. This may also be the reason the company is no longer in business.

Good to know. I'll have to see what I can find.

Also, does anyone know if it would be possible to use a Surly Fixxer (http://www.surlybikes.com/parts/fixxer_pop.html) to turn it into a rear wheel?

Not really. There are two main hurdles:
1) the internal thread showing on the pic is probably bigger than the internal thread that the sury fixxer is supposed to engage.
2) even if by a stroke of blind luck the threads would be compatible your hub hasn't got the splined interface which the fixxer is supposed to fit over. W/o those splined bits interlocking you'd have a "suicide" conversion, meaning that the cog could come off if you put backpressure on the pedals.

Does anyone know if this hub (http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=380153182123&ssPageName=STRK:MEWAX:IT) shares the same bearing seat/bearings as the larger diameter hubs like mine? I call Ben's Cycle but they didn't know much about it.

I'm still on the hunt for info to get this wheel operational.

Someone mentioned that it may be possible to use a Shimano XT hub or just some parts from it. Does anyone know anything about this?
