Tektro R736. Good point though, other dual pivots might work. They'll have to be long reach, I measured a distance of 53mm on my particular bike.

Still love the dual pivots btw, what a great braking upgrade. I still catch myself expecting single pivot performance, so I give the levers a very light pull just to control my speed a bit only to feel them grab and really slow the bike down. Haven't had to panic brake with them yet but I feel much more confident for when I do.
