I think I have mounted those on most any Center pull brake ever made by bending the mounts that attach to the front of the brake. I currently have one on a Universal 61. Cantilevers might be a little low to do the same but I have never tried it. My DAD misordered some back in the day, he wanted 2 but some how got 2 cases . We were real good at selling both those and a TA type handlebar bag branded LEFUMA to the local college boys (I think because a 6 pack fit neatly inside the bag )
