With the cables secure against the bar, you’re ready to start applying the handlebar tape. Remove the adhesive backing strip from the handlebar tape if there is one (typically it’s yellow, and in the centre of the bar tape), and begin wrapping.
There are several different ways to start wrapping. Jon is an exponent of the method demonstrated here: inserting an inch or so into the bar as a first step before beginning to wind the tape around the handlebar. Inserting the end plug as the final step of the wrapping procedure will ensure it remains in place.
Alternatively, you can begin wrapping by laying the tape on the handlebar and covering the end with the next layer of tape. The tension will hold it in place.
It’s fine to wrap ‘inwards’ towards the frame, or ‘outwards’ away from it. The key is to adopt a consistent approach and wrap both sides in the same direction.
A uniformity in the overlap is also critical to a well-wrapped bar. Jon recommends an overlap of approximately half the width of the tape.
