Optimizing length can provide better balance while shorter crossbows can be better suited for maneuverability and tight spaces.
The weight shown on the left is the overall weight without accessories installed, while the weight on the right is the weight with all included accessories installed.
Draw effort is the weight of resistance while cocking a crossbow. Most crossbows require minimal effort to draw with a cocking aid.
Modern crossbows are drawn back with a cocking aid. Excalibur crossbows use attachable cranks, integrated cranks, and rope cockers to achieve as little as 12 lbs of draw effort.
