I got the Woodcraft clipons with a 3 inch rise. I really like em due to the adjustability and ease of installation.
With a 3 inch rise you can go an extra 3 inch above the clamp when the clipon is at the top of the triple clamp.
However if you want to go all the way down to the bottom clamp,the bars will be 3 inch higher due to the rise. Eventually I am going to get the 1inch adapter so I can take the 3 inch rise off when I just want to stay around the house for short rides.
