Hey guys, today I'm going to convert the quill stem system of this road bike to threadless
What size do you need?
Before you begin to order a converter, measure and find out the size you need
The threaded fork is 1" and the inside diameter of the steerer tube is 22.2 mm
The threaded fork is 1 1/8" and the inside diameter of the steerer tube is 25.4 mm
If the diameter is 25.4 mm, you'll need 1 1/8" to 1 1/8" threadless converter
If the diameter is 22.2 mm, you'll need 1" to 1 1/8" threadless converter
The adapter converts your old quill style forks to use threadless stems
The top cap has a standard size of 32 mm
Therefore, you need to install the stem before putting it into the steerer tube
The adapter couldn't go any further
Before you tighten the top bolt, take out the adapter
and grease around it to avoid it from getting stuck at a later time
