Lighter?I've got one on my 100mm TT wheel. A bit fiddly to fit and it doesn't stay flat in places unless stuck down. However I do think it makes the wheel a bit lighter.
Lighter?
Aha! Thanks.Lighter than a full disc.
Why wouldn't it work? As far as physics is concerned it'll be just as effective as a disk, it serves exactly the same purpose.The point with a disc is the rotational affect can help with flatter routes. Too much faff with a clip on, and not convinced they work.

Maybe you should change that to the ones you've come across don't fit very well! I can't actually imagine someone being stupid enough to fit a disk cover and not make sure that it blocks the wind from getting inThey don't fit very well, nor have they been through a wind tunnel (e.g. fit/poor airflow, air going behind disc) . They are an early 90's thing !
