Good Day All,
I returned my Superstar Tesla wheelset due to the freehub failing. Wheelspec:

Been used for a total of 6 months only. Superstar received the wheelset on 10-Jul-13. Here is the letter I sent with the wheels:
I am returning my custom built wheel set in a cleaned and fully stripped down condition for inspection. The freehub drive has completely failed. I have had no issues with the bearings themselves.
I have been running the wheelset on my trail bike for a total of 6 months. The freehub started to slip 4 rides ago with the hub slipping on the initial power stroke but then seemed to be fine, although with some minor slippage at times, for the duration whilst the cranks were moving. It then worsened so that on every power stroke the hub slipped causing the cranks to jerk through the arc of motion. The rear wheel freehub was stripped, cleaned and re-greased using slick honey grease. This proved to be futile and did not resolve the issue. I have attached some photographs showing the damage found to the interior of the hub body: Image 1 - shows wear to the teeth of the freehub wheel. Image 2 - deep cuts on the inner periphery of the hub body.
No harsh cleaners, chemicals or jets of water have ever been used in the cleaning of the wheels (or any other components on my bike).
It was noted that on the initial fitting of the cassette that the correct torque for the cassette lock-ring could not be achieved as the free hub slipped whilst I was using a torque wrench. Although this did alarm me that this could be a potential issue or failure criterion in the wheelset, the drive in the wheel was not compromised at all and I did not investigate further. After the initial shake down ride of the wheel set, I was that impressed that I emailed yourselves and posted a favourable review on your website.
I appreciate that the 'superfast pickup' requires much finer teeth on the freehub body, but this should not come at a cost to the 'bombproof reliability'. The wheels should be able to last longer than 6 months of trail/XC riding before needing to have the freehub body replaced, if ever at all! I have read online of other users having similar issues and would like to know if this issue has been or can be engineered out, as at present the wheels are not fit for purpose.
I look forward to hearing from you and would prefer to be contacted via email.

I received only one reply and that was a week ago:

I have tried ringing superstar but fail to get through and it just goes onto the answering machine. I also feel that I am not being that unreasonable with the time scale because in all honesty how hard is it to take 2 x 5mm hex keys and undo the freehub to technically stare at it? Has anyone else been in this position and had any issues with the Tesla freehubs. I did some looking around and some folks did mention that these are actually a older failed design based on a dmr hub.
