They're generally lousy with loads.
In a commuter bike you want stability and the trade-off is some loss of speed when carrying a load and also when riding on uneven terrain.
Some road bikes do have bosses. The one I linked to, like many others, does not.
There are racks made for such situations.
OP said they are looking for a faster bike than their cx Masi (load carrying ability, stability), specifically a road bike...
