I just took receipt of a new Planet X Dirty Harry frame to replace my defunct Gary Fisher Rig SS 29er. I was hoping at my IS mount Hope Minis with 160 rotors would fit with a post adapter, but there is no chance.

Does anyone have any recommendations of post mount brakes they have had success with on the Dirty Harry or 456 (which looks like the same rear end)?

Thanks
Richard

I have a scandal which uses the same dropouts – a shimano Xt caliper fits fine with a 160mm rotor.

BB7 on my C456

Thanks for the quick response.

Is that the post inserts on the left hand chain stay? I thought the scandal had the IS mounts on the seat stay, but I am sure there have been a few different variations of it,

Cheers
