It provides one other good clue to the bike’s attain, whereas bearing in mind the angle of the seat tube.

KOPS (knee over pedal spindle) is a time period used to search out the right fore/aft. Along with your foot on the pedal and the crank on the three o’clock place, grasp a plumb line from the again of the kneecap — it ought to go by means of the kneecap and pedal spindle.
The saddle tilt is extra a private desire round consolation. Begin by utilizing a spirit stage to get it parallel to the bottom, and make finite changes from there as consolation dictates.
