Which brake model to Use for GIANT ATX One DH?

[DaHaoZ]

Hello everyone. I just bought a Giant ATX One DH frame. I think is an earlier model, because its brake mount is "inside" the rear angle. Please find below the picture.

I had an in depth search on the web. This earlier model should be equipped with a Hope C2 brake. But I know that C2 has many types of "Numbers", from 1 to 11, which made me very difficult to choose.

Is there anyone who could tell me which "Number" of the C2 brake caliper should I choose for my GIANT ATX One DH?



Thank you very much in advance.

IIRC the early ones were Hope No.1 caliper fitment as that was 'the standard' at the time, although I can't remember if this equated to a 155mm or 165mm rotor. Later ones took the IS style and these mounts would have meant No.3 for a 165mm rear, or No.8 for a 185mm. That No.8 was only from the Pro Enduro 4 and on though from early 2001. That was the lighter replacement for the DH4 which had never been available in a No.8, and for your case, neither was it available for the C2 either.
