Rotor options for my BBK
I currently have the Sparta Triton BBK, and will need to replace my front rotors in the near future. Unfortunately, their shop on their website is down and they aren't responding to communications.
They're 380mm x 34mm. Questions: I'm seeing lots of aftermarket 380mm x 35mm rotors, would any of these work or do they need to be 34mm thickness? Would rotor ring replacements be an option? They have 12 bolts, but not sure if there other things I'd need to measure to see if a non-sparta ring could work Thanks!!

Unfortunately it's not as simple as just diameter and thickness. There's quite a lot of measurements as shown in the Brembo image below. The inside diameter and annulus is also important.
This is one of the reasons going for a well known brand of brakes is safer, just for the spare parts availability. |

Thanks for the details! Upon further research it looks like Sparta sourced their rotors from Pegasus here in the USA, so I'll reach out to them directly.

As Redd pointed out above, it's unfortunately not that easy to find iron disc rings that weren't explicitly designed for a given disc hat/bell. Below is a video we shot on why discs are generally not interchangeable. Hopefully this helps you better understand the critical dimensions of the discs you're seeking. Good luck and hopefully this helps! |
