I have bought a second hand 19 inch frame and I am normally used to a 20.5 inch.

The bike rides OK but I would benefit from raising the handlebars.

I have read about fork steerer tube extenders and adjustable bicycle stems.

I personally think the fork extender would be a better way, are there any advantages or disadvantages to either?

    What type of bike is it? (E.g. road bike, mountain bike, city bike) Does your bike have a threaded or threadless headset? The difference is explained in the following answer: bicycles.stackexchange.com/a/10078/30402

A stem with a greater angle and rise, potentially coupled with a riser handlebar will be a stronger solution than a steerer extender. If you are doing casual riding on flat ground a steerer extender is probably OK. If you are riding rough terrain and putting a lot of force through the bars an extender may not be able to handle it.


Are you sure you have a threaded steerer? Like this?

If so, then there are a few options:

If you just want a quick bike fit fix and be done with it, then, as you most likely have a quill stem, get one with higher height and/or angle:

But, if you want a long-term thing and 'get with the times', you can fit a quill stem to threadless adapter:

(2nd image is an expander stem version, but it also works the same)

Though you will also need to buy an actual threadless stem too.

    The "wedge" (first three) stem is generally seen as a more robust and safer design than the "slit and cone" (last example).
