Repairing a carbon disc wheel

Hey folks wish me luck, My E-Bay special $150 disc wheel separated all the way around, where the carbon meets the Aluminum rim(both sides). even though the epoxy and etching system cost almost as much as the wheel. I figure it's still worth the effort, and cheaper than a new wheel. The rim is still attached so I made a cleaning tool to dig out any old glue,then rubbed sand paper in the tight gap,then slid as much cleaning stuff as possable in the gap, the I used a 2 part etching system( as much as I could in the tight gap),Then I squezed the 2 part epoxy in. now I wait for it to set up. tomarrow I will do the other side. I will let you now how it came out, as Sunday I will race on it.

Dangerous was when I rode this wheel for 13 miles next to an unfenced 15 foot dropoff into a cement river wash. I glued the other side today and took it over to get the tire mounted. It's looking good for race day.

Do you have good medical and life insurance? Remember, the cheapskate often pays the most in the end.

Are you serious? These wheelsets typically cost $2-4K. Do you think this is just marketing? Man, you are taking a huge risk. The assembly for these wheels is not a simple process and you are not going to duplicate it at home with duct tape and gorilla glue.

I will totally agree with the responders who asked if your insurance is paid up.

High end bike products are not for just those who can afford the product. The cost of upkeep is not necessarily stated, but it is certainly implied. Expect to pay $200-400 for a proper rebuild for that wheel.

If you got the epoxy and etching system from the wheel manufacturer, I think that you have a pretty good chance of success. But if the system is one that is just put together from off the shelf items and not specific for your wheel you may have big problems. So where did this repair kit come from?

Some more info. Wheel-Aerosport Trialist Disc. Epoxy-3M DP460. Etch kit-West System 860-8 aluminum etch kit. I followed every intruction and precaution I could think of. and the wheel set up really well( within original trueness). Later today I ride it. More to come.

Great job. You obviously have good skills and a very good incentive to make the wheel repair correctly. Since you were able to repair one side and then the other, you were able to get the wheel to stay true without having to have a jig to hold everything together. again great job.
