GT DH Hubsets - 4 bolt rotors?!

shogun · Jan 28, 2013

Does anybody know what bike and brakes this GT-Hadley hubset is designed for? I have seen a few sets come up for sale, and I imagine they're either off a STS-DH or Lobo....Please correct me if you know otherwise.

The PCD of the rotor mounts is 50mm on the front hub and 28mm on the rear.

Ideas?

I would like to pick up a set for my 98ish STS-DH build but I'm not sure if they're the right era or what brakes would fit on them.

I just found this on the net

"that the 'current' 4 bolt pattern is the coda/cannondale pattern. I have several 8 and 6 inch rotors by hope for the coda (old DT/swiss made) hubs.

The Hadley/GT hubs were an older Hope standard that no one really supports. Marzocchi used the hope caliper standard on some of their 97-99 forks but they're not supported much either. I think you may be out of luck unless you can source some old hope 4 bolt rotors."

Hmm interesting.
Best I can tell, the Lobo came with Rock Shox/Amp discs which are 3 bolt, and the STS/LTS-DH came with Formula brakes.

EDIT:

'98 Lobo had Hopes...bikepedia says Hope hubs too?!

NFI what these are meant for then.

Ah!
Think I have it.

Formula Evoluzione rotors:

So they must be LTS/STS-DH hubs after all. Time for some buy-it-now action!

Indeed they do, and it will be either a C2 or Formula Evoluzione for this bike.
