Chain guard for a belt-drive bike? So this morning I'm riding to work on my shiny new tourer, when my trouser leg gets caught in the Gates belt drive. Not good!

I'd rather not go the leg-strap route if I can avoid it, which leads me to ask whether a chain guard or chainring guard exists that would fit over a belt, given that the belt is wider than a chain. The crank is a Shimano Tiagra, if that matters.
There are chainguards that work with derailleur bikes. Your belt might be wider than a chain, but it isn't wider than a triple :-)
Something like http://www.sjscycles.co.uk/hebie-chainguard-for-triple-ring-systems-with-a-48t-outer-ring-prod19993/
(If you've got a 52t chainring, it might be trickier to find something that will fit.)
