@christophertaekim Thanks for reaching out!

This item should work just fine for your bikes. You'll want to look at the REV12 and make sure the current stem is the same size as your REV16. It should be, but you'll want to confirm. If so, then you should be okay there as well. This riser does allow you to adjust the height of your handlebars.

Lastly, you'll need a longer 5mm hex wrench to install.

Hope this helps!
