I have a set of FSA SLK brakes that I would be willing to trade for some Avid Shorty Ultimates or Pauls Neo-Retro or Touring Canti's. The Fork I am using only has one hole for the brake spring and the SLK's come with fairly high tension springs. This combination is wreaking havoc on my hands and I need something with a bit more adjust ability. If you're interested let me know, I have all the necessary hardware and will throw in a fresh set of pads front and rear. They are identical to the brakes in the photo and have the neon green highlight.
