• Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

carbon rims

Aluminum rims bend, carbon rims break.

That said, I have some carbon wheels on my mountain bike and have put them through utter hell. They're still like brand new. I've had the wheels for 12 or so years and the only thing I've had to do is replace the bearings in the rear hub. You can't buy them any more:

Bling Bling!!! I want a set of these SO BAD, but they are more expensive than Marchesini's.
They are carbon fiber overlaid on aluminum and are tubeless.

I posed the same question on that thread and got no answer, so I thought I would ask here. I just didn't see the need for the aluminum backing unless there is an actual need for it. The composite panels on the airplanes at work have a backing, but it's almost foil like in thickness
 
At least on the MTB wheels, the aluminum is there to provide a braking surface. The aluminum hoops are also replaceable, if you ding one. I'd bet if Spin was still making those wheels, they'd have a disc version by now.

They're also pretty flexy. On the street, I can feel the gaps between those spokes. You can even see the vibration in my arms. I use regular wire spoked wheels on the street because the vibration is kind of annoying. In the dirt you can't feel it.
 
For a spoke wheel you'd have to have the aluminum backing because the spokes would pull through the carbon, let alone trying to spoon on a tire.

It would be interesting to know if they actually weigh much less than a standard aluminum rims.

If I win the loto I'll get a set to try. :thumbsup:

probably has to do with the shearing forces put on the rim where the spoke nipple sits.
 
There better be some sort of coating or separator between the carbon and aluminum otherwise the aluminum will corrode. The two materials don't like each other and require some kind of barrier between the two of them. I will admit that they are pretty though.
 
Dymag did a prototype Carbon spoke rim,saw them a few years back on the web,they have gone broke now though
 
well anyways, when i win the big lottery it may need further looking into, right after the pork chop toaster, and the all u can eat bacon buffet
