They did the job ! And I did fit them to 28" wheels, as all it did was to lift them up a bit more. As I am no longer a kid, I could handle that, until i learned how to keep my balance on the bike and everything else.. I got rid of them after about 10 sessions of cycling, so I am really pleased. They are good solid steel and the wheels are not flimsy cheap plastic, but proper solid one. I am a bit on the large side, but I felt completely safe and confident learning to ride the bike using these stabilisers .
