I have a VERO Triple 50/39/30 crankset on my bike (http://www.fullspeedahead.com/produc...03930-CRANKSET). I would like to install a circular chain guard on the outside of the largest chainring, something like this: http://www.ebay.com/itm/160942741021

But, as you can see on the Vero crankset picture, there are no extra holes for the bolts (unless I'm missing something).

Is anyone aware of a similar chainring chain guard that attaches with a different system, like clips or similar?

Thanks in advance.
