Cannondale bad boy disc brakes any hope?

[Tc]

I cannot see how to fit my hope x2 callipers to my bad boy frame! Anyone any ideas?

I think you will need a flat mount to post mount adapter.

The front I kind of understand but the rear holes face the wrong way & the calliper would have to be mounted upside down

 

[davidj]

Rear needs an IS to post mount adapter, front needs a post to post adapter. You need adapters to match the size of your rotors.

Front probably needs post to post 180mm adapter. Rear looks more like IS to post 160mm. The rotors will have their size stamped on them.

Thanks mate that’s perfect & you were spot on with the sizes

Hi, am I able to jump on this? I have a 2018 Bad Boy with the double crown(?) light pipe style lefty. Looking at putting a Hope floating rotor on. Standard is 160mm but wondering if I could upgrade to 183mm? If you know what type of mount I'd need?

 

[davidj]

Hmmm, I thought the Hope 183mm rotors were only produced for legacy compatability reasons and their standard now is 180mm.

I have no idea what adapter would be needed for 183mm but for a 180mm rotor you need a standard post to post 180mm adapter.

If your fork is post mount 160, then you'll need a hope "h" mount.
That's off the top of my head and I'm certain I'm right.

@davidj The one I was looking at was 183mm but your flagging that helped me not buy the wrong thing! So, thank you

@albash82 I've put photos of the mount on the fork. Does that help you make a definitive choice? Thank you
