It can be hit and miss with the trixie wheels to be honest.
Mines not too bad, but I know others have sent them back.
I know it is expensive but the silent runner is pretty much silent.

For a syrian (unless it is a very small one) it is best to get a 11-12 inch wheel.
Someone else may be able to recommend a cheaper silent wheel, but I can't. I know people buy the trixie from amazon so if they have problems they can send it back easily. But I am not sure you can choose which colour you get.
