I don’t understand how to install a quill stem extender. Photo included. I have my stem, the long screw and the wedge. The stem extender on the right has a stem, a long screw, and a wedge. The screws hold the wedges on. I’m confused. I put the stem extender in. But do I leave the screw? Then how does my stem go into that? And no screw is long enough to reach through it all. I really don’t understand. Do all wedges and screws get used?
Sorry - you have the wrong part, or need a second part to make it all work.
The item on the right is a quill stem to threadless adapter, and if you used it to replace your current stem it would effectively be lower, and also require you to buy a stem
I'm not aware of a quill-stem extender, and if one was made it could end up quite wobbly, and too close to the chest.
Your other option is to fit new handlebars with more "rise" to them, in that they swoop-upward more.
I was in the exact same predicament, same items, same confusion.
There is a very easy solution. You need a longer quill.
You're raising it up so the Quill/Wedge that attaches to bike stem would have to be longer as well.
Measure your quill. I think all standard ones are 6.5”/165.1mm so the riser I got was 2" higher (8.5”/215.9mm). Couldn't find 215.9mm but 230mm okay (9"). I just bought one at https://www.universalcycles.com
Good luck if you still need it and happy riding!
If you have a quill stem extender here's how it should be installed.
I always put wheel bearing grease on the wedge - all sides - and bolt where it threads into the wedge. This prevents rust and assures that both the extender and the stem can be removed in the future.
- The quill extender is inserted all the way into the fork and the extender bolt tightened.
- The stem is inserted into the quill extender and the stem bolt tightened.
I recommend a longer stem rather than using an extender
