I couldn't get these to fit my bike. They have a square end that keeps them from sliding all the way in. Not really sure what they would fit. Very poorly designed.

I couldn't get these to work on my bmx bike at all so I'd say they could have Ben shaped differently. I'm happy I got them but maybe they can go on my mountain bike...?
