Stirrups is a technology in Age of Empires II: Definitive Edition that is unique to the Bulgarians and can be researched at the Castle. Once researched, it increases the attack speed of the Scout Cavalry line and Konniks by 25%.
Note that Dismounted Konniks are unaffected by Stirrups.
Strategy
Mounted Konniks have the slowest melee attack in the game, however, after researching it, the Konnik´s attack rate drops to 1.8 which is the same of the knights, and Konniks have higher base attack than knights and also can be created in the kreposts, so in the castle age this technology is a must research if the player wants to utilize them, Through is a quite expensive and Blacksmith technologies should be prioritized at first place. In a post-imperial basis, Elite Konniks attack faster than Paladins, this combined with their easy creation and and being able to fight dismounted, makes the Konnik one of the best cavalry units in the game, as well one of the finnest Unique Units.
Stirrups also affects Light cavalry, and in a similar way, puts their Hussars at a huge advantage in "thrash wars" ., also probably makes a fully upgraded Bulgarian hussar the strongest in the game and able to defeat in one-to-one combat generic hussars, Mongol hussars, and even Malian light cavalry with Farimba.
