@Vi60,
I have already answered your question in the other thread. Due to the nature of
specialized stems used in different Vado models (Specialized Flowset in 4.0 & 5.0, Specialized Stealth in EU 6.0) the only practical way to raise the handlebars is using a standard straight "A-HEAD" 1-1/8" threadless stem extender/raiser of height of 65 mm. Here is a good news for you:
All Vados --
regardless of the stem construction -- follow the A-HEAD
standard of the MTB (also of road-bikes). Here's how to install the stem extender:
This is a good A-HEAD stem extender/riser:
It is vital that the cables have enough slack after installing the extender. Provided spacers allow to regulate the stem height (the stem does not need to be raised to the maximum). It is also important that the long vertical bolt is tightened with such force that the handlebars can still be rotated freely but no slightest vertical movement of the steering column is allowed.
The practical outcome is you will sit in far more relaxed position on the bike even if the extender is relatively short. The reach will be shortened with an inch and that will also help to sit more upright.
