does it come with the riser part of the strap?
No, it does not come with the "ladder" part of the strap. It is meant to be a direct replacement on any Burton binding that does not have a cap-strap.
However, most local shops carry the ladder pieces and will sell them to you for around $5.
On a separate note, most other companies toe straps can be adjusted should you want to use this on a Non-Burton binding. All you usually need is a pair of scissors or a knife... if you want it to look like an expert hack-job maybe use a dremel tool.
I have fitted many non-burton bindings with this strap!
