AndyT Posted September 8, 2022 Report Share Posted September 8, 2022 I recently ebayed some nice saint hub rear wheel for a vintage build but didn’t realize that it came with a shimano oversized centerlock rotor that they only made for one year (2011??12?) for this saint hub Any options to find one? The normal channels have no luck, can i buy a 3d printer and fab my own? do the new printers work w steel yet ? i guess no rear brake for now..

Swoofty Posted September 8, 2022 Report Share Posted September 8, 2022 Rule #1. Just say no to centerlock. Any centerlock. Now you know why that hub was $10. :-( Good luck. Quote Link to comment Share on other sites More sharing options...
La Bourde Posted September 9, 2022 Report Share Posted September 9, 2022 That is sad to see how the acceptance of Center lock is. A lot of brands are not able to produce parts that fits correctly due to the tight tolerances required. And yes, Shimano itself made CL even more complicated. Centerlock is from a mechanical point of view a much superior standard. First, the interface with the hub is much wider and the surfaces in contact bigger. This allows to conduct the forces better, to prevent a disc to twist (the rotor could be much more stiff) and to align the disc perfectly (some 6 holes hub use bad tolerances and thus unalign/twist the rotor). Having a bigger contact surface allow a better head dissipation too, but we don't care in trials. From a safety point of view, centerlock is also better, cause even if the rotor is no longer maintain by its lock ring, it can't fall off and one can still brake. But the tolerances of the hub and the rotor are tighter and thus companies can't produce cheap components by ignoring tolerances, like they do with 6 holes mount.

I'd be looking at getting a 6 bolt adapter waterjet/laser cut and sacking off the CL... I can't imagine anyone bothered making aftermarket for that setup and chances are Shimano hardly made any spares either. A metal 3D printer will set you back many thousands of dollars and are still incredibly specialist and just not an option. You could design the part and get it made by Shapeways or similar but chances are that will take a few attempts and still cost you a few hundred dollars to get right.

MadsP Posted September 10, 2022 Report Share Posted September 10, 2022 Had the same problem some years ago, and learned about the rare oversize version. The oversize rotors are still possible to find. I believe the model name is SM-RT80. Here are a couple of examples: Quote Link to comment Share on other sites More sharing options...
MadsP Posted September 10, 2022 Report Share Posted September 10, 2022 If you want the 160mm version it is called SM-RT80S: Quote Link to comment Share on other sites More sharing options...
MadsP Posted September 10, 2022 Report Share Posted September 10, 2022 … btw be aware that the oversize lockring takes a specific oversize tool: Quote Link to comment Share on other sites More sharing options...
