Hi Doug, They will work on the Sunrace mounts with a very slight bit of filing to the mount. I think this was documented in an email from Will, but can't remember exactly. Basically there is a small tab on the face of the mount where the bottom of the lever would sit and that little tab needs to be filed off.
Hope this helps. Rory Oakland, CA -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
