Thanks for your questions about fitting Quick Caps to the seat post.
We have trialled and tested various seat post quick release clamps over the past few days.
Right now we can say that although it does fit some of the seat post we tried, the design will have to be altered to be a product that we would feel comfortable sharing.
It will however be a future product to add to the Quick Caps product range.
Thanks for your support all, we are nearly half way there!
