Oliver, came across your post whilst searching for information about LIYANG.
It should be worth a fair amount to a collector as it was one of the first carbon frames in production. They retailed at £450 new and were produced about 12 years ago.
I have one also and have upgraded all componentry to produce a very light commuter, with pace rigid carbon forks, shimano xt and low time trial bars.
If you still have the frame, I would be interested.[email protected]
If not enjoy as it was a great frame, and should last for years.
