The first group of numbers (to the left of the vertical line) describe the upper part of the headset while the second group of numbers (to the right of the vertical line) describe the part of the headset that will fit into the bottom of the head tube.
The first letters ‘EC‘ refer to the type of headset being described and is explained above.
The second set of numbers ‘ 34‘ refers to the size of the hole in the top of your head tube where the headset cups or bearings will go.
The second number “28.6” refers to the diameter of the fork where you will clamp the stem. Most contemporary bikes use the ‘28.6’ size which is a 1 1/8″ fork.
