Expert Reply:

The RockyMounts MonoRail 2 Bike Platform Rack - 2" Hitches # RKY10004 could technically fit your 2015 Subaru Forester's 1-1/4" receiver when used with the Hitch Adapter # 80303, but using this adapter will reduce your trailer hitch receiver's capacity by 50%. This will likely not allow enough weight capacity for the RockMounts carrier (38lbs) and your two bikes, but it will work if your combined weight will be under 50% weight capacity of your receiver.

If your combined weight is going to be over 50% of the receiver's capacity then I would look into the Hollywood Racks Destination Bike Rack for 2 Bikes # HLY94FR. This fits 1-1/4" and 2" receivers and is also compatible with motorhomes. This carrier attaches to the bike's frame so that it fits many different types of bikes, including those with fenders or baskets. The weight capacity is 35lbs per bike and it fits tires up to 3" wide. I attached a demonstration video.
