So I dinged up one of my rotors causing it to rub. I tried to true it, but figured this is a good time to upgrade from the Formula rotor. So, I bought a replacement. All I checked was 180mm and 6-bolt design. Big mistake #1 (oh yes, there's more)!
For starters, the bolts holding my old rotor on the rear wheel were torqued on really tight. They are extremely shallow Torx bolts and of course with 6 to loosen, I stripped one. I was able to take a hammer and force a hex bit into the hole and remove it, but the screw is ruined. Thankfully, my new rotor came with screws (wait for it).
Hooray, the old rotor was off. All I have to do is put it on the wheel, put the screws back + 1 of the new ones and I'm all set, right? WRONG!
So, the motor wire comes out on the brake side...*sigh* and it is protected by this odd sorta half moon shaped looking thing. The hole in the new rotor wouldn't and couldn't fit around it.
This is what I bought:
This is a Formula One rotor:
Anything that looks like the first picture will never fit on your rear hub motor Turbo, sadly. It needs the clearance of the larger opening to clear the half-moon-motor-protector-thingy.
So, I put the old rotor back on. Did my best to straighten it and for testing, borrowed one of the screws that came with the new rotor. Big mistake #2! The screw was longer than the original. No biggie? Well, after putting the wheel back on, I realized it would no longer turn. It was that pesky long screw. So off the wheel came again (boy I'm getting good at that) and now I have a rotor with 5 screws until I can find a replacement.
When I get another replacement, I'll post some photos and maybe a video, if I have time. Time to go to sleep.
