Gearing is really important. The general rule of thumb is that a half of a pedal stroke should move your bike one bike length. I choose to run 22 teeth in the front 17 in the rear. This gives you a good amount of torque when you’re doing moves from a stand still and let’s you time out pedal strokes for gaps and drops when you have a short runway and need to squeeze in as many revolutions as you can. The chainstays on the STP are adjustable from sub 16" to sub 17". I run them at to make the bike as nimble on the back wheel as possible.
