So I've got two different sets of cantilevers on hand and I'm trying to decide which to put on my 1983 Fuji tourer. The first set is Deore LX. The other is Avid Shorty 4. Both are used but appear to be in great shape. I've already mounted the Deores but just got the Avids at a swap and I don't know if I should try those out instead. Anyone have any thoughts on this?
