I have a 58 cm quickbeam that I used to have set up with suntour xc pro brakes. In order to use a nitto M12 front rack I used the Paul rack bolts. This puts the rack too far forward and requires a spacer on the threaded fork crown attachment point. This outward cantilevered position paired with overloading my front bag and hitting one too many potholes caused a rack failure for me. (The rack's threaded rod broke underneath the spacer.) You think that I would have wised up after the first one, but I bought a new M12 and this time used the Nitto rack bolt and Mafac brakes, unfortunately in order to keep the rack level, I still needed to use a spacer, the second rack broke the same way as the first about a year later.
Finally, I wised up and switched to an M13 (narrow) rack and used Mafac Tandem brakes (same geometry and mounting style as the Tektro that Bill recommend). This rack is more re-enforced at the fork crown and I was able to mount it without any spacers. That rack never let me down. My Quickbeam is now in a rackless single-speed cyclecross formation, so I still have the M13 rack. It's available if you happen to want to go that direction. But, yeah. Listen to Bill. I wouldn't mix off the shelf Nitto canti-post mounted racks and the Paul rack bolt. Oh, here is a picture of it with the Mafacs and the M-13: https://flic.kr/p/n7oK6g And previously, with the Mafacs and the M12. https://flic.kr/p/bNC8Pa Best of luck, Sam McCune New Haven, CT -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
