Back a year or two ago when I was designing our bike - I had considered Magura Brakes. At the time I developed a button "Like the Cat Eye" to fit in both the extension bars and bullhorns (to also sell to Cervelo owners that had Maguras on their bikes). Its still ready to go - but when I could not get the Magura's to work in our front fork - I shelved the project.
