Same thing happened to my wife, the bracket broke on a big bump. Torhans did replace the unit but not very confidence inspiring. In addition to needing to use duct tape to prevent the bike from getting a Gatorade bath.

I have no idea if the Vision is as good aerodynamically. My wife uses it and doesn't have a power meter. I might borrow it some time and do some field testing but frankly have other things that are higher on my list and don't get that many low wind days for testing.

Any idea why it's black? Seems like that would heat the contents...
