Please do not reply with "roll up pant leg and cover with sock" or "use velcro strap", I have done both. The purpose of my post is to find a solution that doesn't require the preparation of the previous two methods every time I want to ride.
I believe that 48T is the largest chainring size on "Trekking" cranks and the largest officially supported chainring size for most MTB/Trekking FD's. There are very few flat bar shifters and front derailleurs that support more than 48T, and the market for chainguards among the drop bar and brifter segment is probably very small. This is probably why SKS and Hebie chainguards have 48T as maximum.
There are chainguards for 52T and above, but they are usually of the "ring" /bash ring type that replaces the outer chainring.
You may be able to find a so called "chain disc" in size 52T. The largest I know of is Kool Stops Chain Disc that goes to 50T.
It wouldn't be that expensive to change the outer chainring to a 50T so that could definitly be an option to consider.
This chain guard from VO allegedly works with 50T chainrings:

Perhaps a good starting point for DIY solution?
